Shark Attack Horror?

 
Really - have you seen this shit?
 
Andrew is obviously totally correct, the comments are total rubbish.
He was cornered by an eager "reporter" and like we always do lest there be any misunderstandings, asked that any questions be sent to him by email.
Alas, that obviously never happened.

So there, let me try to put things into context.
  • First and foremost, Mark is apparently going to recover OK.
    He's a real nice kid and we wish him the best of luck and a speedy recovery.

  • He was however not merely free diving, he was spearfishing.
    As shown in literally countless examples, this can frequently lead to shark bites. Like I said many times eg here and here, it is well known that the Sharks in popular spearfishing locations like Frigate Passage can get highly conditioned = aggregate at the mere noise of a speargun being fired, get highly excited by the vibrations of a speared fish, try to nab any catch and retaliate when poked and pushed away. This is most likely what has happened here.
    In brief, do not fight with a Shark over a fish!
    To cite myself (talk about being prescient!)
    And if you spear fish and are not careful, you may well end up having one of those close encounters described by Jonathan - not because of us but because that is what happens everywhere around the world, see here and here among many, many such examples!
  • The Shark was most likely a Grey Reefie.
    But it could also have been a Silky (no that's not a Bronzie - nor is this one!) or a Galapagos - case in point here! Bronze Whalers however are essentially antitropical and not officially recorded from Fiji.
  • The Shark feeding dives have nothing to do with this, zero.
    Once again, we have actually collected the scientific evidence that clearly illustrates that with the exception of our small harmless Whitetip Reefies, our Sharks
    a) were never resident but have instead always spent most of their time roaming throughout Fiji, and most importantly,
    b) have never depended on our handouts but have instead remained wild animals that have always continued to normally hunt their prey away from the Reserve.

    In brief, the fact that we feed less (yes we do still feed) has no incidence whatsoever on the well being and/or the behavior of our Sharks = they are not going hungry nor being more aggressive nor roaming further afield or anything like that - and again, this is not my opinion but evidence = fact!
    Read the links!

    And one more thing.
    Some quarters have suggested that our fed Sharks may have lost their natural fear of humans and may therefore have become so-called beggar Sharks and thus, more dangerous. We do not observe any of that when we dive without bait in the Reserve, and it thus makes no sense whatsoever to assume that it may be happening further afield.

    Again, the people who have conditioned the Sharks to approach spear fishermen are not the Shark diving operators but... the spear fishermen themselves!
  • And no, this is not about testing let alone predation!
    Those smaller Sharks simply don't prey on humans. Instead, the bites are most certainly agonistic = due to competition and/or aggression and/or self defense/retaliation - read this about agonism and this about Shark attacks.
There you have it.
In brief, Fiji's responsible Shark feeding operations have zero effect on the safety of the population at large - re-read this.
 
Long story short?
Sadly, this is nothing more than shoddy journalism that instead of bothering to engage in even the slightest modicum of objective research and fact finding, is merely repeating some random unqualified and unsubstantiated speculation and hearsay. And by being unnecessarily sensationalistic and misleading, it contributes nothing to the safety of the public and is also bad for the Sharks.
Not impressed, sorry!

Better next time Fiji Sun!
 
PS: really interesting comments section here = note how there's none of the usual gratuitous drama. And Setareki's reminder of the ubiquitous poaching and illegal selling is obviously spot on. Like I said back then, we know the perpetrators and also the enablers, and there will be a reckoning.

PPS - Bingo: watch this - fundraiser here.
Having actually gone and asked Mark
  • He was indeed spearfishing

  • It was indeed a Grey Reefie

  • The Shark was exhibiting the typical agonistic display of this species and then attacked twice, as they do. This also tells me that it was probably not a tourism Shark as those are used to people approaching them and have never, ever displayed agonistically during any of our feeds.

  • And finally, beware of the charlatans and self professed experts on social media - really, what a sorry bunch of total losers!

Shark Attack in the Red Sea!

Remember?

This is bad - watch in HD.



As to what exactly happened.
Apparently there was no bait *- and for once I tend to believe that. 
One very knowledgeable friend speculates that the victim may have gotten in the way of the OWT who was targeting the dude in the shorts, and that the OWT did bite him in order to chase away a perceived competitor in what would be a case of agonistic behavior.

I beg to differ: to me this looks like a quintessential predatory attack
What strikes me is how small that Shark is, meaning that it may be a subadult who is still experimenting, or not a very good hunter and thus particularly famished, or just a particularly bold individual - but of course we will never know as per this unforgotten brilliant post by Rick.

Story here.
If there is some lesson to be learned from all of this, it escapes me ** - maybe with the exception of the fact that playing possum when faced with a pesky predator may not be the best strategy!

Anyway.
Let's go Shark diving!

* or maybe there was?
** or maybe not = read the rather shocking comments in the above link!

Investigatory Bite?


And I cite,
It [the shark] opened its massive mouth and as it's closed its mouth it kind of ripped down as it went to swim away," she said. "There was one metre [missing] off Callum's body. 
I was horrified, then I realised it was just the fin. We're just lucky that it was an investigatory bite and didn't involve any missing limbs. Once we got back on the boat I was pretty upset and a little bit shocked, but it's a really beautiful encounter with out of our most revered apex predator" 
Right.
What a load of horse manure - beautiful encounter my ass!

No that was not an investigatory nibble.
That was a predatory attack, and like they often do, that GWS was trying to immobilize its prey and went for the propulsion; and the dude is really incredibly lucky that he merely lost a fin and not his leg. Seriously, can we please  stop the bloody whitewashing and finally let Sharks be Sharks.

Thank you.

Shark Attack - Video!


Watch - scary shit!



Yes that would be an ATTACK.
Not mistaken identity, not investigatory but predatory.
Yes I'm clearly speculating because it could also have been agonistic - but going for the propulsion is a typical hunting technique, and I'm sticking with my opinion.
This is a rather small animal, possibly a subadult transitioning from a piscivorous diet to also feeding on pinnipeds; and with no parents to teach it, this is likely a period of trial-and-error before, maybe, becoming more discerning - or not!

And try it certainly did!

Reunion Island


Beautiful in so many ways.

I must say, I was really touched.
Story here - and especially here!
Enjoy.

Red Meat?


Watch.



Yeah that would be a Shark attack.
It happened because, and I cite,
"Sharks like to eat fatty red muscle...” David said.
Indeed - especially Whale Sharks and Angular Roughsharks!
I mean, seriously, that statement has the same truth content and educational value as if I professed that Mammals like to eat Eucalyptus leaves - meaning plus/minus zero! Like Cristina (brava!), it really bothers me that we put all ‘sharks’ into one pigeon hole and ascribe the same basic behaviours to them all, seldom realising that there are more than 400 species of different sizes, living in different environments and showing different behaviours!
And then, I read
So why do sharks bite?
Shiffman says it’s usually a case of mistaken identity. “Sharks aren’t used to things being in their environment that isn’t food. When a surfer cuts through the water on his board, wearing a white suit, he can easily be mistaken for a seal,” he says. But most of the time, once a shark gets a taste of his bony human dinner, he backs off in disgust. “The ‘hit and run’ is a common bite — they take one bite and realize it’s not what they wanted to eat,” Shiffman said.
Really.
Same old same old, and equally totally misleading - except that apparently, surfers now wear white garb! I can categorically assure you that the Blacktips and Spinners that strike surfers in Florida and the Bulls doing the same in Reunion Island are NOT mistaking them for seals!
Likely, the Floridian Sharks act in perceived self defense or are maybe caught up in a feeding frenzy (read this!); and equally likely, those Indian Ocean Bulls are engaging in predation - but of course we will never know for sure!
Bravo David for the laudable intention of wanting to put Shark strikes in perspective - but the stubborn ultracrepidarianism, and this from a self-proclaimed dragon-slaying myth-busting fact-based researcher is really irritating!

And that Blue Shark?
Judging from the head shake etc, methinks this is an attempt at predation - but again, who knows. But divers hovering next to bait bins whilst being obviously oblivious of the dangers and of their surroundings are a recipe for disaster. If this is a fun dive, then OK, shit happens - if, like it appears, this is a commercial dive with tourists, then those lousy protocols need to be changed, pronto!
Remember this shit? It gets triggered by stuff like that!

Anyway, just sayin!

PS: thread here - agree agree disagree who knows! :)

Ritter - appalling!


Damn the guy!

I was actually enjoying my blogging retirement.
But this shit and specifically, his underhanded description of that infamous predatory attack by a Bull Shark cannot remain unanswered.
Here is that attack.



No the attack did not happen because the spotter did not do his job.
It happened because (read it - brilliant!) a stupid self-promoting Sharkitarian who had developed the inane hypothesis that they would not bite him as long as he would lower his heart rate, or whatever, decided to wade around, bare-legged, among a pack of feeding Bull Sharks!
I mean, seriously!

And the worst thing?
Despite of the fact that the Bulls Shark disproved his inane hypothesis, camera running, he continues to spout the same pseudo-scientific drivel til this day - and some poor suckers in Germanic Europe believe him and continue to give him money! Case in point: if you can, you may really want to experience the truly epic masterclass in snake oil salesmanship in the YouTube series prowin- pro nature donates 50 000 U$ for Erich Ritter's SHARKSCHOOL e.g. here.
Simply amazing - both the indisputable craft of Ritter and the naivety of his credulous victims!

Anyway.
There's a sucker born every minute, nobody else cares, and he is and will forever remain the laughing stock and pariah of the Shark research community. I just feel sorry for poor gullible Amin who will inevitably end up like all those other gullible past foundations, sponsors and philanthropists, see below: um teure Erfahrung reicher, and tainted by association!

But back to the spotter.
Here's what he had to say when confronted with the allegations.
What a sad and pathetic little man!
Perception is nine tenths of reality to someone like this guy! Ritter, you have always done your narcissistic "martyr" act far too well!

I think back at the events of that day and see him flexing his muscles in an Arnold Schwarzenegger pose while stating loudly for the two cameras...."We aren't afraid of no stinking sharks"!
This was his response to my telling him he should get out of the water as the tide was slack, too much bait and blood was in the water and we could not control the sharks safely after already having several close calls. He looked at me and laughed! My crew and I exchanged worried looks after his comment.

But the Discovery crew said to Ritter..."we only need 5 more minutes of B roll" and Ritter, who was always a whore to the cameras, said "no problem"!

5 minutes later I was fighting to save his life....and did so thru rapid and definitive means.
I still have the blood stained belt I used to tourniquet his leg. I held him in my arms in the emergency flight I had on standby and kept him from going into shock. I stopped the paramedics in the US from reopening the wound when they wanted to ogle a shark bite by pulling off my clot producing dressing that kept him from bleeding out, and sat the day and night in the waiting room thru his surgery and recovery to make certain that he would be OK. He walks to this day because I saved the hanging torn muscle in his leg when others told me to leave it but I wrapped it into his wound and that muscle was surgically reattached and allows him to walk and run without a limp and continues to work his ankle to this day.

He will never know that I got the Walkers Cay company to give him $10,000 for his recovery and a year later when they decided they wanted repayment of that loan....I fought them hard to back off and leave the man in peace.
They agreed.


So as the "spotter" who you blamed for this horrible misfortune in your "little man's life" I say this.
You should thank me Eric for "giving" you a "war wound" which has been your only meal ticket and the only thing that gives you any credibility among the misguided groupies that you pander to. It certainly has not been your scientific insights in shark behavior or papers full of pseudo scientific drivel that has earned you any acknowledgements.


My crime was that I was loyal to you.
Something you know so little about based on that rambling dissertation I just read! You managed to burn every bridge with every solid individual that wanted to believe in you and who would have launched you into a viable scientific career.

Sadly Ritter....You just can't fix stupid!

Thanks for allowing me to rant!
Mike, feel free to print this if you like. 
Gesagt getan!

Bull Shark Attack - pretty darn stupid!


Oldie but still epic!

Seriously - what were they thinking?
Trying to "control" a big Caribbean Bull Shark (= a Sardine) by wrestling it like on 0:36ff was always gonna be a recipe for disaster, and re-hooking an already pissed-off animal with Nick in the water was criminally negligent - and what ensued, the inevitable consequence.
And yes this would be a (provoked, retaliatory) attack - probably even for Neff and Hueter!

Anyway, check it out!

Shark Harbour!


Remember this post?

This is now the finished product.
I must say, I am rather impressed by how they have managed to successfully negotiate the pitfalls of reporting about the controversial subject of Shark attacks by analyzing them from a principally scientific viewpoint. The researchers come across as totally knowledgeable and objective and also, respectful of the animals and emphatic with the victims.
I commend Michael Lynch and his team for a job well done - especially when juxtaposed to those horrible comparable productions by Discovery!
Kudos!

This is a full-length feature so relax, lean back and enjoy!

Excellent Interview by Barry Bruce!


Check this out.
As we continue to be bombarded by a deluge of self professed Shark experts with pavlovian on-camera reflexes, Barry Bruce of CSIRO stands out as extremely knowledgeable, reasoned and highly compelling. This is one of Australia's foremost researchers of Great Whites who has collected numerous tracks that show how Australia's GWs migrate north along the Eastern seaboard and to WA at specific times of the year, possibly following their prey.
Barry is also the man behind the call for less Shark diving operators and Shark diving days in Neptune Island, South Australia, this based on objective data gathered during years of research into Australia's Great Whites, video here.
Andrew Fox agrees so it's probably OK.

But I'm digressing as always.
Enjoy the interview - this is as good as it gets.



Further compelling statements against the Shark cull in WA
Tip o' hat: the Dorsal Fin.

Sunday, October 23, 2011

Australia - kill those Great Whites!

Australia - back to the 50ies

Well, what can I say.
There has been another fatal Shark attack off Perth and it very much looks like the authorities have resolved to order a Shark cull.
It will achieve nothing - but it will likely placate the public and be the lesser evil when compared to other measures like anti-Shark legislation. No don't get me wrong, I hate it - but with people like this idiot stirring the pot, some kind of a political knee-jerk reaction was all but inevitable.
Talk about a timely post by Patric!

Anyway, not good and very much q.e.d.- alas!

PS much the same, much less polite here.

Shark Feeding Rubbish from Down Under!


Here we go again - and yes, I am livid!
I was having a real nice, mellow day - and now this.
This is what you get when moronic reporters, or whatever, interview moronic Shark experts!

No, I'm not gonna bother to post a full exposé.
I've blogged ad nauseam about feeding Sharks and I would be totally wasting my time trying to formulate yet another novel response to the old tired moronic allegations.

So this time, let's do something different.
Please re-read this.
Then, re-read this.

Then, have a look at this shit.



See?
The token Sesselfurzer (no, not a PhD!) has released a few more farts.
And then we got ourselves a veritable diving underwater medecine expert, Dr Carl Edmunds (Navy School of Underwater Medicine and South Pacific Underwater Medical Society) - who has been personally diving in the SOPAC no less! Wow, talk about impeccable credentials - after all, a PhD is a PhD, and who gives a shit about the totally irrelevant detail of the discipline it was obtained in! Tell 'ya what: how about an even more impressive veritable diving PhD (!) in quantum physics (!) next time!
And how about Mr. Hoy himself asserting that keeping (and feeding!) Sharks in an aquarium is a hell of a lot better for the Sharks! Compared to? Obviously, free Sharks being offered the occasional snack!
Just Great!

I say, show me the F@$%ing Evidence!!!
Are there more Shark attacks on Flinder's Reef?
Have there been less Shark attacks after the Florida ban?
Right!

Notabene: the above obviously with the exception of Pensacola where the life guards will henceforth be able to avail themselves of the unparalleled (!) spectacular eco-behavioral insights of the world's ultimate Shark expert, ladykiller (for German groupies only - alas!) and I read (!), owner of Sharkwater, Erich Ritter!
Talk about a prudent and at the same time, highly effective and outright visionary investment of taxpayer money - especially now in the recession!
How cool is that!

But!
Did I hear
There were reports of increased activity around the beaches, including reports of Great Whites circling fishing boats waiting for food?
Indeed! How many fishing boats are dragging in struggling Fish that send around irresistible vibrations all across the ocean? How many fishermen standing on the shoreline which last time I looked, includes the beaches drag in struggling Fish that send around irresistible vibrations all across the ocean? How many spear fishermen operate close to shore and shoot Fish whose death throes send around irresistible vibrations all across the ocean? And, how many of those folks clean their catches, throw the scraps into the ocean and create irresistible chum trails in the process - and this always in the same place, like the entrances and inside of the harbors and marinas? Remember Walker's Cay? Hell, in Hawaii they even conduct Tiger Shark viewing dives in one of those places!
Compared to how many Shark diving operators?

So who, exactly, is conditioning Sharks?
Let's ban all fishing and spear fishing!
I wish!

Have a nice day!

PS: thank you Patric! Rottweiler huh... :)
PS2: Wolfgang on the Sesselfurzer in 2007!

Undercurrent on Shark Feeding!

Yes we feed Sharks - Terry-fic pic by Terry Goss!

Gotta hand it to the folks at Undercurrent.
Starting with the idiotic title, they have managed to post the by far most preposterous piece of utterly stupid anti Shark feeding shit published by a dive magazine, ever.

WTF has happened?
What has possessed Ms Richardson to provide a platform for the ramblings of the anti industry zealots instead of trying to remain impartial like in the past? Tell you what happened: she clearly doesn't have the slightest clue about Shark behavior (poor innocent Cristina's Caribbean Reefs are not solitary but gregarious) or the Shark diving industry and its protocols, and is obviously increasingly believing and parroting what the clowns she is interviewing are feeding her.

Case in point, Ralph Collier.
No Vanessa, Ralph is neither a researcher, nor a scientist.
He is the prototype of what the Swiss call a Sesselfurzer, as in "someone who farts from a couch", very much reminding me of the Shark-hating voyeuristic parasite. His claim to fame is to head his Shark Research Committee (are there any other members?) whose only research consists in recording GW attacks on the Pacific coast of the US and publishing the statistics in a series of forgettable amateur publications. Like Ritter with whom he shares an affiliation, or whatever, to the SRI and the GSAF, he is the ultimate Shark pornographer who professes to be furthering Shark conservation but then ultimately reduces Sharks and their life history to one single aspect, that of Shark/human interactions, meaning Shark attacks.
Having been elevated to rank of "Shark expert" by the misguided invitation of the Egyptian authorities, he is now obviously basking in the limelight and being invited to run his mouth on topics about which he obviously doesn't have the slightest shred of knowledge, let alone expert competence.

What Collier spouts is not new.
It's basically a textual rehash of his interview on the atrocious Red Sea Jaws where he asserts that feeding Sharks will lead to attacks on innocent bystanders. The "proof": one single video showing divers hand feeding one single OWT with Fish stored in a fanny pack - which according to Collier has led that Shark to subsequently attack the hands and buttocks of two victims, leading the great researching scientist to derive a general rule pertaining to all Sharks in the Red Sea!
Howz that for taking intellectual and methodical shortcuts!

So we're looking at a shark habituated to human beings for getting food, and humans had taught the shark where the food was. And this occurred frequently in the Red Sea. With overfishing in the area, sharks have to come up to the reef area to feed, and now associate food with the human form. It's very much like training your family dog. When it sees your hand, it sits up to get a bite of that treat.

Right!
That's EXACTLY what trained family dogs do: they sit up whenever they see a hand (notabene, a hand that does not hold any food!), meaning all the time, and when hungry, they run out of the house and randomly bite the hands (and very possibly even the ass!) of passers by!
Which obviously begs the question, does Collier own a completely crazy dog - or may he be simply pompously bloviating without the slightest knowledge about the behavior of either dogs or Sharks.
You be the judge of that.

The rule is simple.
To know about the specific behavior of an animal, you need to observe that animal when it is engaging in that specific behavior, and this over an extended period of time. If you unable to do so (and I betcha that Collier's personal experience with Sharks is limited to maybe a few cage dives with GWs at best), you need to talk to the people who do, or read what they publish on the subject.
The people who feed Sharks and who observe Sharks that are being fed are some divers, several Shark diving operators and a handful of Shark researchers - and thousands upon thousands of fishermen and spear fishermen!

Surprised about the latter?
Fishermen do not only feed Sharks by presenting them baited hooks; many of them attract and often end up feeding Sharks when they drag in struggling fish and when they subsequently clean their catch and throw the scraps into the ocean. Spear fishermen are notorious for attracting, and even conditioning Sharks when they shoot fish and often find themselves embroiled in a competitive struggle over their prey. These people number in the hundreds of thousands and if anybody should be examined for possibly causing an increase of Shark attacks on the public, it should be them - not the few dozen operators conducting baited Shark dives!

But I'm not here to deflect and obfuscate.
I'm certainly not about to give you the spiel about how we, the Shark diving operators educate the public and contribute to Shark conservation, as it got nothing to do with the issue at hand. The issue at hand is whether divers feeding Sharks leads to an increase of attacks on people who do not partake in those events, like Collier asserts.
That is a testable hypothesis.

The first of the possible tests is simple.
A. Are there more Shark attacks on the public at or around Shark feeding sites compared to similar control sites.

Let me start with a pathetically trivial statement.
In order for there to be a Shark attack, a person and a Shark will have to be in the same place at the same time. Thus the incidence of attacks will inevitably depend on the following variables: the number of Sharks and the number of people present in a determined location; and also, the activity and behavior those people and the Sharks are engaging in.

With that in mind and considering that feeding Sharks will aggregate some species, one would indeed expect an increase in Shark attacks in the vicinity of Shark feeding sites - but when one analyzes the details, it is not quite that unequivocal.
In 12 years of feeding Sharks here in Fiji, we have witnessed
  • a staggering increase in the number of Bull Sharks that roam wide ranges but regularly visit Shark Reef once they have discovered that it's a good place;
  • a negligible increase in the number of the much more resident Greys, Whitetips and Blacktips, a species that does not roam and is thus not likely to be attracted from locations afar;
  • but then, a decrease in the number of intermediate Sharks like the Silvertips, Lemons and Nurses, and possibly even Tigers;
  • and with the exception of one single fly-by by a spooked Great Hammerhead, zero sightings of any other species, this despite of the fact that we regularly introduce 2-300 kilos of yummy bloody bait and despite being situated on the fringes of 300m deep Beqa Channel and of Beqa Lagoon that are all being prowled by a plethora of other Sharks like Zebras and Hammerheads but also pelagics like OWTs, Silkies and Duskies.
And what about Shark attacks?
There are only two Shark feeding operations in the country, Beqa Adventure Divers and the guys down the road, and we both conduct our Shark dives on the southern coast of Viti Levu facing Beqa Lagoon. Documented Shark attacks in the vicinity: a big fat zero, ever.
The few documented Shark attacks have happened in Taveuni where Tigers Sharks prowl the coast of the current-swept Somosomo Straights; in the mouth of the Sigatoka River where surfers insist on frolicking on a break despite of murky water and the occurrence of large Bulls and Tigers; and in various locations where spear fishermen have defended their catch, often at night.

Anybody wanting to venture a guess about the results from elsewhere?
More importantly, would any of the bloviating Shark attack experts please care to comb his collection of data in order to prove or disprove a causal connection? Maybe for once act like what they purport to be, forgo their idiotic ad hoc speculation and engage in the onerous task of following the scientific method instead?

B. What about the risk of Sharks biting people during Shark dives?

Let's go back to the above trivial statement and variables.
When it comes to baited Shark diving, the obvious, and equally pathetically trivial rule is this.
  • the more Sharks are present, the higher the risk of a Shark bite
  • the more divers are present, the higher the risk of a Shark bite
  • the more dives are being conducted, the higher the risk of a Shark bite
  • the closer the divers and the Sharks interact, and the more frequently those interactions occur, the higher the risk of a Shark bite
So, yes, unequivocally, Shark diving increases the risk of a Shark biting a person!
And the question of baiting versus non baiting? Yes, of course baiting increases the risk, as it draws in more Sharks and leads to closer interactions!
Duh!

The consequences? Please re-read this.
Some divers are happy to experience Sharks when and where they occur naturally. Others wish to predictably experience other species that are highly skittish and/or do not aggregate naturally and thus need to be attracted with bait. Assuming that baiting does not harm the animals, and so far, nothing indicates it does, it's not a matter of prohibiting baited Shark dives, it's a matter of ensuring a maximum of safety by adopting the best possible safety protocols!
Is there a residual risk - yes of course there is, especially for us in the front line!

But what about the motivation for those bites?
Please re-read this. It is, to the best of my knowledge, what we know about why Sharks bite people - and please correct me if you think I'm wrong.

With that in mind, I assert that nearly all of those bites are not predatory in nature.
Contrary to the plethora of bloviating Sesselfurzer, I look back on nearly 40 years of diving and on thousands of Shark dives, most of which in baited conditions. In all those dives with dozens of different species in different situations world wide, I have never been in a situation where I had the impression that a Shark was sizing me up as potential food, not one single time - and incidentally, everybody in the industry I have talked with shares the exact same observations.

I have however been subjected to multiple threat displays, this by Grey Reefs exhibiting agonistic hunch displays, by Silvertips becoming stiff and jerky and more recently, by large dominant Bull Sharks gulping and ramming me with their snout.

I have also witnessed several Shark strikes.
All but two were by Sharks biting the people directly handling the bait. All of them were characterized by one or more of these factors: competitive, frenzy-like situation; bad visibility; lack of concentration/distraction of the feeder; feeder being bitten in his left hand which was holding more bait; non-dominant, sub-adult animal barging in.
The two remaining strikes were retaliatory bites by Silvertips on people denying them access to bait, very much like the famous incident where a Silvertip bit Dinah Halstead in PNG.

Consequently, our procedures include the following
  • all divers wear dark full body wetsuits and especially, dark gloves as pasty white hands sticking out of dark wetsuits may be mistaken for bait, especially in low visibility
  • we maintain a clear separation between the customers and the Sharks
  • the feeders wear chain mail gloves to minimize the effects of accidental bites
  • we hand feed in order to always control the bait and to be able to withhold food once we deem that the animals are starting to behave competitively. In situations that become too tense, we temporarily interrupt our routine, retreat and wait for the animals to calm down again - which incidentally, they always do
  • the feeder is flanked by bodyguards monitoring any dead angles and gets rotated out after ten minutes in order to prevent lapses in concentration
  • there is only one feeder acting as the focal point for the animals, and he only ever holds a single piece of bait
  • we do not feed in bad visibility of less than 10 meters and are particularly alert when the visibility drops, as we have observed that this is when the Sharks (who do not see through murky water any better than we do) tend to be particularly edgy as they have to rely on their other, less precise senses when approaching the feeder
  • nobody but us approaches the bait bin, ever
Which brings me straight back to Richardson's stupidity.
It mentions two Shark attacks, that on Groh and that on Jimmy.

Jimmy was apparently bitten by a Caribbean Reef, a competitive, edgy and strictly piscivorous species, whilst handling bait in murky conditions. These to me are perfect preconditions for a mistake by the animal.

Groh was apparently positioned right next to the bait cage, meaning that the Bull Shark that bit him may have been engaging in behavior aimed at deterring a perceived competitor.
Furthermore, once the Shark destroyed the bait container and a lot of sand was kicked up in the process, it was trying to navigate in very reduced visibility and water saturated with fish juices, thus losing its sense of orientation and possibly mistakenly biting the first solid object it came across, i.e. Groh's leg. Was it really exactly so - dunno but it is certainly plausible.

And the Ritter attack?
The interpretation of what triggered it (= a stupid guy doing stupid things with macro predatory Sharks) keeps changing but to me, it's rather irrelevant anyway: this is clearly a predatory attack where the animal first tested and then devoured Ritter's calf.
Accident my ass!

C. Last query: are Sharks that are being fed by divers (and what about those that are being fed by fishermen and spearos?) more prone to bite people than unfed Sharks.

This is what Collier is asserting and Richardson is parroting - and of course what is being really asserted, is that fed Sharks will not engage in just any attack, but that they will be conditioned to perpetrate predatory attacks on humans.
This is of course a tricky one to document - notabene one way or the other!

There is of course no such thing as a generic "Shark" engaging in generic "Shark behavior".
Instead, Sharks are very different behaviorally both when it comes to species but to complicate matters, even when it comes to sex and age within the same species, all the way to pronounced individual character traits that can be shaped by individual experiences.
Also, the behavior of a species can be very different in different locations or at different times of the day, etc.

But having said that, I can share the following.
Our flagship species, i.e. the Bull Sharks that frequent Shark Reef have been fed for the past 12 years and are undoubtedly one of the most conditioned population of predatory Sharks on the planet.

Bull Sharks are very timid and hardly ever approach divers.
But we want our customers to experience them, and this is the reason why we resort to luring them in with bait, and to reward them whenever they approach one of our feeders in the way we like, i.e. from the left and slowly.
This is called training by positive reinforcement and I can assure you that contrary to all the pledges to the contrary that are meant to appease the tree huggers, all Shark diving operators feed the Sharks when trying to attract species that are shy and in locations where those species do not aggregate naturally. Teasing only just does not work long-term as the animals are not being rewarded and will simply stop coming.

It is thus fair to state that by feeding our Bull Sharks, we are conditioning them to approach people and thus engage in behavior they would not normally display.
But here's the catch: we observe that unlike Collier's demented family dog, our Bull Sharks will not simply approach just anybody: instead, they will only approach determined people, and this mainly only when those people are proffering food!

Example?
Look no further than when we are training a new feeder. For weeks on end, he will be standing next to the bin brandishing his treats - and the Sharks will look him up but never take a single bite! Talk about an exercise in total and utter frustration!
Eventually, a single animal who is very likely not one of the old-timers but instead a newbie who doesn't yet know anybody else will take a first offering and be forever linked to this one particular feeder. Only over time, some of the other Sharks will deign to come in for a snack, however really only when they have no other choice because their favorite human happens to have a day off.
Incredible - and yet, it's totally true!

Or here's another example.
I've been diving the Fiji Shark Dive since 2003, first twice and now, up to five times weekly.
I never feed the Sharks. What I do, is to observe and film them as part of our ongoing long-term monitoring. Over a very long period of time and by proceeding in very small increments, I have been able to attain a status whereby the Sharks appear to tolerate and at times largely ignore my presence, allowing me to roam freely among them without any discernible effects on their behavior.
But when people other than me or Rusi venture in front, the Sharks will inevitably retreat - unless we accompany them, and even then, their behavior will be decidedly more diffident!

And lastly, we observe this.
We frequently dive Shark Reef for other reasons, be it in order to service our moorings or because we are monitoring its health and changes in the composition of its population of Fishes.
The Bulls live deeper in the channel and when we don't carry any bait, chances of seeing them are extremely slim and limited to occasional fly-bys by single individuals. We have even mimicked the exact dive profiles of our Shark dives, as a control, and thus without any bait - again with the exact same result that the Bulls were simply not interested.

So much for the assertion that fed Sharks will approach and attack people - and this after 12 years of conditioning them to the presence of divers!

Granted, this only applies to the specific Bull Sharks that frequent the SRMR.
But until somebody comes and proves that a specific individual Shark that has been fed has increasingly attacked people in un-baited conditions, nothing will ever convince me that what I'm experiencing in Fiji does not apply to all Sharks that are being fed by divers anywhere!

There you have it, that's my take - thanks for your patience in trying to follow my rant.
Still think that Collier is an expert on Shark attacks in the Red Sea?

And what about Undercurrent?
Looking forward to reading Part number two - and very much hoping that Ms Richardson will start talking about the real problem that is besieging Sharks, i.e the global fishery targeting their fins! Not that I believe she will after this total fiasco.
But then, as they say, hope springs eternal!

Doc and Amr Ali on the Red Sea Shark Attacks!


Check out the videos.



Mr you-know-who: didya hear the part about the likely causes?
Sheep carcasses?
Bah!
And Doc's explanation of Shark attacks? Brilliant!



As always, stellar messaging by Doc - and I must say, also by Amr Ali, the Managing Director of the Hurghada Environmental Protection and Conservation Association (HEPCA), a local (and vocal) environmental NGO!

I cite:
It's not the tree hugger approach that will make the Sharks survive... it's the economics of the whole industry, the diving industry and the tourism industry, that will protect these Sharks.
Wow!

Incidentally, did you catch on to Doc's little side remark?
Good to see that Sharkproject boss Wegner has finally come to his senses!
Once very much one of the cronies of Herr Doktor Ritter and consequently, an implacable detractor of Doc, he is now obviously um eine teure Erfahrung reicher - like everybody else!

Yes I'm digressing as always!
Bravo Doc and bravo Amr!

Bravo Doc!

Patric is right - great pic by Daniel!

If threatened by a Shark - hide among the coral!
This, and more life-saving tips on Shark-human interaction in this remarkably stupid feature on the Voice of Russia.

Thankfully, there is Doc - see the comment!
And no, I got nothing to add!

For once!

Upon further Reflection!


There’s something I wanted to share with you.
Whenever I post something a little more substantive, there’s obviously a lot going on behind the scenes. This time, I have been severely reprimanded – and been caught out as a total ignoramus in the process!
Remarkable!

Nah it’s not about one of my rants.
In fact, those who have earned my respect and thus, the right to criticize me rather like my rants. They know me and know that I have zero (make that −273.15°C) tolerance for stupidity, hypocrisy, bullshit and lies and that I consequently loathe such things as political correctness, new age whackoism, conspiracy theories and religious piousness - and above all, all facets of pseudo-, alternative- and anti-science! They also know that my rants are generally motivated by my own ethical imperatives rather than tribalism or obscure secret agendas of world domination and the like. In my former incarnation, I was a staunch proponent of meritocracy and its inevitable consequence, accountability, and I thus pride myself in being an equal opportunities blamer and praiser – actually, with an emphasis on the latter!
But I’m digressing as always.

No, surprise surprise, I got slammed for this!
Looks like whilst trying to sort through all of that pseudoscientific speculation, I’ve committed the exact same sin I criticize in others!

The contentious issue: my endorsement of this interview with Avi Baranes.
Indeed, I must confess that I’ve been caught up in its overall pro-Shark messaging and have completely failed to properly analyze the specific content of what was being said!
Mea culpa – totally!

My critic will remain unnamed – no, you won’t be able to guess!
Suffice to say that he is highly intelligent and that he totally knows what he’s talking about - and that he shares my passionate aversion for bullshit!
I re-print his critique verbatim, albeit slightly abridged to preserve his anonymity as this was never meant for public consumption. But I do find it highly instructive - and personally, rather humbling! My self esteem is rather, for lack of a better term: robust (did anybody say pompous ass?) and this has definitely pricked that cozy bubble! Somewhat!

Anyway, I wanted to share it with you, if only to show how easily the discourse can slip into utter irrelevance, scientific and otherwise – and this even when the interviewee is a pro who certainly knows better!

So, here's how a brilliant analytical mind has dissected that little interview.
The critic’s comments are in blue.

Enjoy!

********

This interview is not the words of a scientist trying to place sharks in proper perspective. It reminds me of those people that think sharks are nice and need to be invited to tea. Sharks are not nice or mean—as Da Shark said—they are sharks.

In an interview with Haaretz, he sought to make clear that "sharks are actually quite nice." Avi Baranes
Dec. 7, 2010 (Nir Keidar)

Dr. Baranes, the shark attacks we've seen in Sinai recently are considered rare, but three such attacks have been reported in rapid succession. Why is this happening?


It's true that a violent confrontation between swimmers and sharks is an exceptional event. I think there have only been two cases in all our history: with a British English soldier in 1946 and an attack in Eilat in 1974. Unfortunately the film "Jaws" gave sharks a bad name, and unjustifiably so. Many more people are eaten by dogs than by sharks, and this is because sharks are uniquely attached to their own particular food.

More people are eaten by dogs than are eaten by sharks because sharks are UNIQUELY attached to their food????
This assumes that feeding ecology is the sole motivation of why all sharks attack people. I would argue that the evidence does not bear this out. So it can not be that dogs eat more people than sharks because sharks are attached to their food.


So, when there are incidents like this, we have to look for a cause. Sharks attack people when they invade their territory, and then their reaction is aggressive, as it is when they are unable to obtain their natural food.

Territory and aggression are very loaded words.
When a great white bites, kills and consumes at fur seal is the shark being aggressive (one of the “big five” drives) or is it motivated by feeding? Sharks are actually rather unaggressive animals tolerating one and other very well. Even intraspecific aggression is rare in sharks—think feeding in a bait ball.


Most rapacious sharks do not appear to hold territories although they carry a personal space around with them.
Dr. Baranes is mixing up his terms and strongly confusing the issue as well as being just plain wrong considering what we know of social behavior of sharks. Then he finishes this tour de force by stating that they become aggressive when they can’t get their food!
Oh Pleeeeeze!!


Essentially Avi is stating unequivocally why sharks attack and gives the reasons---territoriality and aggression!! Hi suggestions are not even that reasonable even in the light of our poor knowledge of shark behavior. Just think of all the divers who would die with such a behavioral repertoire—aggression and territoriality---when humans enter the water.

In 1974 in Eilat, a Mako shark attacked a German tourist. The shark was caught the next day and it turned out that it had a problem with its spine and could not swim fast.

Now here we see a forensic determination of why this mako fed on the person.
It may or may not be true. However we have seen all sorts of deformities in sharks including blind ones and plastic-ensnared ones that are doing just fine. So while it might be true that the shark could not feed properly it is just a theory not a fact.


This was a shark that usually fed on tuna, and it simply could not obtain its regular food.

What is the regular food of mako sharks?
In fact they have a relatively wide feeding ecology with prey spanning the gamut from marine mammals to cephalopods. I am sure that even a damaged mako can find food or else it world die rather quickly being warm bodied. I can accept the explanation that Dr. Baranes gave but it sounds to me like the experts simply wanted to come up with a reason for the attack that made sense. I would love to read the report to see just how they determined that the shark could not find and catch its “regular food”. Remember: scientists should be skeptical by nature just like attorneys—show me the evidence!!

In Sinai I know of cases where sharks simply bit the legs of Bedouin fishermen who were standing on reefs. This is the response to an invasion by humans into the shark's living space, and this can also happen when divers enter their territory.

What? No!! This is yet another unsupported conclusion.
What if the shark happened to bump into the fisher? I have seen small sharks on the flats swim right through the legs of waders and they might have been bitten if they had frightened them at that moment. So anything from fear to aggression---rare in sharks---could be operating in this example.

Shark territory reaches right up to the beaches in Sinai? Sharks do not apparently hold or defend territories like damsel fishes. Perhaps Dr. Baranes means shark habitat. Territory is a very loaded term.

The Red Sea is one of a kind. It is narrow and deep and that means that whereas in the Mediterranean, sharks are found only in the middle of the sea,

I do not believe this at all.
Avi is apparently mistaking all sharks for pelagic sharks. There are plenty of littoral sharks in the Med. Here is a nice discussion of chodricthyan zoogeography in the Med.


in the Red Sea they can arrive close to the shore. If you go out 50 meters in Eilat, you are already at a depth of 100 meters, so big sharks can get pretty close to the shore. They also approach areas where food is accessible, and by this I mean port areas.

So is Avi saying that shark attacks can be expected to occur more frequently at Port locations?
Is Sharm a port where garbage is thrown? If so wouldn’t sharks be attacking all the time? Actually there are plenty of big sharks like grey reefs that can and do stay close to shore whether there is a drop-off nearby or not. So having the pelagic zone is not a prerequisite for big sharks like great whites or tiger sharks to come close to bathers.


Unfortunately, we use the sea as a big garbage dump.
Three years ago we caught a tiger shark on the northern shore of Eilat and in the laboratory, I found a smaller shark, about 1.8 meters in length, in its stomach, as well as a sheep's head, two chickens, a nylon bag and two unopened jars of mayonnaise.

But why does this not surprise me?
Tiger sharks have perhaps the widest feeding ecology (broadest trophic niche width) of any large rapacious shark and are notorious for feeding on offal. Check the stomach of a copper shark or grey reef and tell me about garbage. By the way you do not have to kill a shark to find out what is on its stomach!


What about Mediterranean sharks?

The Mediterranean is very shallow and so when sharks approach the beach, they are usually females in spawning season who have entered shallow waters to spawn their young. Shallow water is not amenable for large male sharks to swim in.

OK Mike you tell me about whether Avi is blowing smoke here—shallow water not amenable to males? What?

Can you compare the different species of sharks in the Mediterranean and the Red Sea?

In the Red Sea, the temperature does not go below a certain point, so that the corals produce reefs, a kind of refuge for all kinds of marine life. I would say that 80 percent of the fish in the Red Sea live on reefs - a kind of highly accessible food pantry - and so the sharks patrol along reefs. We have 26 species of shark in the Red Sea, include thing Leviathan shark, the largest of all, which pays visits in April and May. It is 12 meters long, but not dangerous. Of the 26 species, there are maybe two that are capable of attacking people. There's no need to make a big deal about this.

Pardonnez moi!
Any shark over 1.5 m is capable of attacking a human. Whether they bite depends on the situation! Even a little 2 kg carcharhinid sharks can bite the sh-t out of you if you grab their tail!!


OK—gotta go. I have highlighted the egregious parts. Happy Holidays

The Mediterranean has more species than the Red Sea, and that's where the great white shark [the star of "Jaws"] can be found, rather than in the Red Sea. To date, there has been no damage to the shark population in our areas, but those in the Mediterranean are under threat because of a reduction in the number of fish. If something is not done to give the fish a chance to recover their numbers, the big predators will be in danger.

Today we have, in partnership with the UN, established an organization to protect sharks from extinction. All Asians love [to eat] shark's fin. They make soup with it, which the Chinese claim strengthens virility. It's true there are lots of Chinese, but that doesn't necessarily make this claim true. Thousands of tuna are used to catch sharks each year; the hunters take the fins and throw the rest back into the sea, and the damage is enormous. Luckily in Israel the shark is a protected animal.

What do you recommend to reduce and prevent shark attacks like the ones we've been witness to recently?

Protect the sea.
Don't turn it into a garbage dump, and prevent pollution. A lot of sewage flows into the sea, and the minute you damage a system, a lot of species are hurt and disappear. It's like a Russian nesting doll: The big swallow the small. If you damage a coral that serves as a refuge for small fish, not only will they disappear, but and whoever feeds upon them will also disappear, and so on down the line,
until the big sharks can't find food.


I suggest we not be afraid of sharks.
We must respect them, and we can look at them in the water. I also suggest that we
refrain from trying to attack them because they will respond and they have the strength and the means to defend themselves. Just enjoy the view. There is nothing more beautiful than a shark swimming in the sea.

Red Sea - the Experts have spoken!


Did you miss me?
I was marooned in Tonga and no, things there have not improved!

In the meantime, wondrous things have happened!
I’m alluding to my last post about the Red Sea Shark attacks: 28 comments and nobody has hyperventilated or insulted anybody! It’s really a good thread and I invite you to go read it as some highly experienced and intelligent people have shared remarkable insights and entertaining anecdotes.
Very cool indeed!

Also, the experts have published their expert opinions.

Haven’t heard much from Doktor Ritter (hear hear Biminibill!)
All I’ve found is this interview where he has looked at some pics and come to the following spectacular eco-behavioral conclusions

To call this an attack would be wrong. I would call this an accident.
The bite marks I’ve seen on the pictures look like the Sharks were defending themselves. The accident might have happened as follows: first, the Sharks took a bite in order to test the smell
(sic) of that creature – in the same way that we touch something to test its consistence. Then, the victims defended themselves, at which the Sharks took a harder bite because they felt threatened.

Meaning that next time a Shark bites you, let him nibble and do not fight back!
Wow!

But then, as I’m about to post, I find this !
Again: Wow! Talk about armchair sniping from way out there in left field! And no, I’m not gonna waste my time, and yours, in commenting on the content, the arrogance, the bullshit. If by now you haven’t caught on to this particular con, there’s nothing I could possibly say that will sway your mind anyway!

Which leaves the other three musketeers.
Quite honestly, I was looking forward to their statements with considerable trepidation: after all, if the only PhD (this is wrong) has already come up with this kind of rubbish, what was I to expect from the lowly naturalists?

So there.
In a private post, George Burgess says this.

From Sharm El Sheik, Egypt.

….. For those of you disturbed by the unscientific nature of the subject do not read on (or wait until these results appear in a scientific journal). Others may find the results of my investigation of interest. ……...

From Cairo


.....
The attacks were unprecedented in scope – five in five days (two each on Tuesday and Wed., one on Sat.); major trauma, the last a fatality; all from nearby locations; unlikely attackers for shallow-water attacks.
Three of the non-fatal attacks involved major injuries (loss of limbs) and the victims were very fortunate to survive.


Here’s the kicker: two of the attacks were by an oceanic whitetip and two by a mako (likely a shortfin).
Note the use of “an” and “a” – there is conclusive evidence that a single individual whitetip was responsible for two of the attacks, including the fatality, and a single mako almost surely was involved in two separate attacks. The fifth attack was by a carcharhinid - it may have been a whitetip, perhaps even the same one implicated in the other two, but not enough evidence at this time to say for sure.

The whitetip incident is, I believe, the first documented case of multiple attack by a single shark, although others have been suspected.
Will check on this more when I return and can access the ISAF database.
The oceanic whitetip was identified by distinctive color patterns and a bite mark on its upper caudal lobe in underwater photos of the shark taken just before/after one attack and other photos taken from shore during another attack. The attacker also was tracked to other dive locations post-attack via photos taken by divers. It was a big one - 2.5 m – that also threatened other divers prior to its first attack.

The similarly-sized mako first attacked a wader (!) in hip-deep water then bolted back over the top of the reef into blue water only to reappear a minute later and perhaps 10 m away from the first incident, attacking a snorkler.
The first victim got away with some lacerati
ons; the second was not so fortunate, being mauled on both arms, losing one.

All five attacks occurred in depths no more than 20 m deep.
A very strange situation indeed. It appears that the disposal of sheep carcasses by sailors bringing a load of live sheep in through the nearby shipping channel may have played a part in this, as may have unseasonably high water temp’s.


More to come as we sort through some other data.


In the past, I’ve not been very kind to Burgess.
He does come up with some highly speculative and also, irritating statements - but to his credit, like him or not, he is the go-to man when it comes to Shark attacks. And this time, I must really say that I am impressed! This is interesting, refreshingly factual and also, it does not dwell on gratuitous speculation.
Well done!

Which brings me straight over to this.
You may want to notice that the press release is authored by Collier, an amateur US West Coast GW attack investigator and by Levine, a travel agent, plus 3 unknown Egyptian (?) officials - and no Burgess!
There’s much I could say here about professional qualifications, fake academic affiliations, ongoing feuds and jumping guns & stealing shows – but then again, is anybody in the know surprised?
So, for a change, enough said!

Let’s instead focus on the merits of what is being said.
First and foremost: well done for not having tried to whitewash this – these were indeed genuine, and very likely predatory attacks and not accidents or mistakes or the like!
I also like the reference to the increase in the population of aquatic recreationists augmenting the chances of encounters, and to the specific topographical features whereby the water gets very deep close to the shoreline.

The remainder? Hmmm…

  • The sheep carcasses? Indeed, maybe. But then again, the only confirmed occurrence appears to date back to the end of September which makes for a rather tenuous causal connex to events unfolding two months later. Or not?
  • The depletion of natural prey due to overfishing? First, from everything I hear, the species most targeted and thus depleted in the Red Sea are pelagic Sharks rather than pelagic Fishes, thus leading to the exact opposite conclusions – but granted, I don’t dispose of the numbers and may indeed be wrong. Which of course begs the question whether this assertion is supported by any specific data? Second, I’m hearing the implicit assumption that “Sharks” will go anywhere and eat anything if they are hungry, very much like the proverbial Bears and Wolves are said to approach human dwellings during particularly harsh winters and the like. But Sharks are not Bears and Wolves. With the exception of a few large generalist feeders like Tigers, most Shark species occupy very specific ecological niches where they have evolved to be successful hunters of very specific, in this case pelagic prey. Conversely, individuals that would stray to hunt outside of their ecological niches would be comparatively unsuccessful, meaning that evolution would have selected against this kind of behavior (and incidentally, one could argue that anyway, those Bears and Wolves would still be roaming well within their original habitats from which they were displaced by our invasion). Look at the Med and the North Atlantic: well before the comparatively recent craze for Shark fins and according slaughter of Sharks, fish stocks in those waters were severely depleted - and yet, I don’t remember witnessing any consequent notable increase in Shark attacks. I remain skeptical.
  • Fish feeding attracted the Sharks? Maybe – and if so, I would suspect that the attractant might have been the commotion rather than the fish bait (what was it anyway: bread and the like?). Then again, I have the exact opposite experience here in Fiji. Shark Reef sits on the edge of Beqa Channel that drops down to 300m and where given determined meteorological conditions, there are regular sightings of both Tuna and OWTs – and still, in more than 10 years of baiting with massive amounts of food creating a huge commotion, no OWT has ever visited the reef! See above, reef habitats are simply not the ecological niche of pelagic Sharks, full stop! In brief, way before attracting any pelagic Sharks, the Fish feeding on the coast would have first attracted the local coastal Sharks, among which the ubiquitous Tigers – and obviously, it has not! Again, I am highly unconvinced!
  • Shark feeding? Do I once again hear that Sharks fed by humans will learn to feed ON humans? This is boring – but if you insist: please, do re-read this! Having said this, there is however one caveat: shark feeding does aggregate Sharks and if conducted in the wrong place, e.g. in the vicinity of swimming beaches and the like, it will contribute to increasing the chances of encounters between the Sharks and the aquatic recreationists – and if conducted in the wrong way, e.g. by triggering feeding frenzies, all bets are off anyway! Is this is true and the guys were feeding the Mako, they were really asking for it! As Richard points out, it is very much the responsibility of Shark diving operators to choose the correct locations and procedures, and rogue operators need to be taken to task! Again: snorkeling with large predatory Sharks is just plain stupid - and talk about this having been prophetic! Alas!

This is plenty dangerous enough!
  • Temperature and metabolism? Yes most Sharks are poikilothermic - but it just so happens that the Mako as a Lamnid like the GW is not! Plus, despite the intuitive plausibility of such a hypothesis: are there any data supporting the assertion that Sharks will eat more when ambient temperatures rise, and if so: concerning which species? My personal observations certainly don’t support that hypothesis. Rather, they lead me to the conclusion that instead of falling into a feeding frenzy, Sharks that feel too hot will re-locate to where the ambient temperature is more to their liking, and that different species prefer different ambient temperatures. For instance, in Cocos, the Hammers will always be found just above the thermocline, meaning that in an El Niño year, they will stay deep and during a La Niña, very shallow. Or to take another example, Juerg’s research on the Bulls seems to indicate that they prefer to reside in water between 25 and 27 degrees Celsius. Conversely, our Reef Blacktips seem completely adapted to the much higher temperatures on the reef top. Different Sharks have evolved to function best in different habitats and temperatures and when those parameters change, they just do not behave like mechanical automatons but instead, re-locate to where conditions are best for them. And then, there’s this: many pelagic Fishes like Tuna are highly migratory and fishermen know that both they and the pelagic Sharks that follow them are associated with specific thermoclines, both in terms of depth but also in terms of how warm water expands from the Equator in Summer and contracts back in Winter. With that in mind, would it not be much more plausible to assert that the unusually elevated sea temperatures may have contributed to aggregating both the Sharks and their prey in the Northern Red Sea?
Yes I’m speculating – but so are they!
The fact is that two different species of pelagic Sharks (forget Ritter) have attacked several snorkelers and a wader (!) on the coastline.
This is truly absolutely exceptional and cannot be suitably explained by the usual generalist sound bites about Fish feeding and overfishing – if causal, both would have led to attacks by coastal Sharks first.

So bear with me if I come up with my own set of wild speculations – and let there be no doubt that my guess is as good as anybody’s and that we’ll never know what really went down anyway.
  • An environmental effect, likely the unusually high temperatures, caused pelagic Fishes and the pelagic Sharks that prey on them to wander into the Northern Red Sea
  • An “event” caused the Sharks to approach the coast, the most likely being that their prey went there (think Sardine Run), or that indeed, a Sheep carcass floated there - or the prey dispersed or was consumed and the Sharks approached the coast when swimming one of their typical search patters
  • The stimuli (think splish-splash) sent out by the snorkelers attracted the Sharks who then attacked

And after these simply brilliant deductions (If you can't dazzle them with brilliance, baffle them with bullshit), I herewith end my posts about the Red Sea attacks!
Hopefully!
