Caribbean Reefs and Parrotfishes!

When people talk about “keystone” species, they’re generally thinking about predators that shape the behavior of every other creature in their habitat, or about prey that serve as dinner for the entire neighborhood. But a new report on the collapse of coral reefs across the Caribbean is a reminder that entire ecosystems can depend on species that do little more than graze.
As in Parrotfishes and Sea Urchins!
This truly epic report details how the Caribbean has lost 50% of its Corals since the 1970s, and suggests strategies for their recovery - the most astonishing one being the need to restore Parrotfish populations!
Not necessarily Sharks tho it will certainly help, too!



Synopsis here, executive summary here.
Required reading!

Sea Shepherd - milking the Shark Cull!

Oh yes, this would be another Shark Operation - remember?

Have you seen this?

It's the usual tried-and-tested MO.
Having squandered heaps of donor money, made a lot of noise and achieved A Big Fat Zero like always, Sea Shepherd now want more of your money. For something that has already been done better and pro bono by others who have then posted it online so that everybody could watch it for free.

And money they will get.
Didn't we just mention PT Barnum yesterday?

Oh well.


Small Hammers in Malpelo - brilliant Video!

This is great.
To me, this looks like an aggregation of subabdult females and males, likely before the reported sexual segregation.

Enjoy!

Discovery - messing with the Researchers!


The Shark researchers are up in arms.

And Discovery are having a ball.
They keep pushing the right buttons, elicit the usual indignant verbose Pavlovian responses, and are being handed heaps of free advertising for Shark Week in the process.

Guys, seriously - you gotta stop being suckers.
Just ignore those provocations and simply stop mentioning that shit.

MPO's Mako!


Wow.

And knowing the man, there's many more pictures where this one came from - minutes or not!
A MASSIVE (in the truest sense of the word) female Shortfin or Longfin (should know soon) Mako Shark estimated at easily 13-14 ft. and 1,000 lbs. 
The blue sharks, which disappeared immediately, looked like toothpicks next to her. 

Reportedly the largest Mako ever seen by dive operators in Pico, this enormous shark rocketed from the blue below and swam among us until we ended our dive - in minutes . She was so big at first I thought she was a Great White Shark (a close cousin). 

The Mako is the top predator in the pelagic (offshore) marine habitat, preying on a variety of big fish (tuna, billfish, etc.) and even marine mammals. 
And this place has plenty of both. 

Unfortunately, sharks like this are becoming harder and harder to find because of fishing. I have to say it's the most impressive shark I've ever seen, and this encounter ranks as one of my top experiences in 3,000 dives in 22 years. 

Truly spectacular - check out the mating scars.
The head is pretty much all teeth.
So what is this - Longfin or Shortfin?
Methinks the latter - alas!

Manhattan Beach - common Sense?

This just not cool - source.

Good one!



Could not agree more.
It's not about the ordinary anglers - it's about those guys that have upped the ante and are recklessly, and illegally targeting the big game right in the middle of the crowds. And yes, the swimmers and other aquatic recreationists need to be mindful of what's going on around the pier, and stay clear of those fishing lines - and vice versa!

Shark Repellents - the Bible!

Shark repelling Batspray in action!
 
Wow.

Talk about a monumental tour de force!
If you ever want to talk about Shark senses and Shark repellents with any degree of competence, you must get your hands on this simply epic treatise on the topic!
Very impressed!

No I'm not gonna try and write a synopsis.
It's simply too monumental, complex and exhaustive - and when it comes to the finer details, I'm also too stupid!

Just this.
I really had to laugh out loudly when reading the following.
Taking a different approach based on his experiences diving in the western Pacific, marine biologist Walter Starck developed a black-and-white banded wetsuit that was intended to mimic the banded poisonous sea snakes that many sharks appeared to avoid eating (Doak 1974; Nelson 1983).

Whilst T. obesus appeared to be unaffected by the banded wetsuit, it was reported to have a repellent effect on C. amblyrhynchos, C. galapagensis, and silvertip sharks (Carcharhinus albimarginatus Rüppell, 1837). Doubt was cast on the effectiveness of the banded suit based on testing performed in the Marshall Islands in the northern Pacific Ocean, but these negative results might have been because the test sites were not inhabited by sea snakes, and local shark populations may not have had the opportunity to learn to avoid them (Nelson 1983). 

This controversy also serves to highlight the difficulties in assessing repellence when complex multi-sensorial cues are available and the problems inherent in testing shark repellents when sharks must be induced (with food) to interact with them. The repellent effects of some devices may be subtle and provide a useful level of protection against unprovoked bites under normal conditions, but may be significantly reduced when sharks are provoked into feeding, especially when in groups (Gilbert 1962).
Bingo!
Even if we choose to forget the WA Tiger Sharks that target Sea Snakes, and Marine Dynamics' zebra decoy - how many Banded Sea Kraits does a GWS typically encounter in his lifetime?

And the funny disquieting part?
Hart and Collin are the very researchers that are lending scientific credibility to that whole Aussie wetsuit scam where the marketing team has even got the audacity to go and praise themselves on self-congratulatory and eminently deceiving TED talks

So what is this. 
Honesty in peer-reviewed articles - but then, aiding and abetting the brazen profiteering?
May this be a case of, gasp, integrity vs money?

Questions questions - but do read that article!

Don't buy Tramadol!


Here we go again!

I'm being spammed by a deluge of messages selling that shit.
Those fucking dimwits don't appear to notice that not a single one of their comments ever makes it onto the blog, and continue undeterred, for days and weeks on end.

So, don't buy that crap.
It's being marketed by total morons, and the side effects are just simply unacceptable.

Eat THAT, assholes!

#SHARKWATCH - good Article!

Source.

You got to read this.

It's an excellent synopsis of global Shark conservation efforts.
Bravo Alan Boyle - job well done!

She's pregnant!


And huge!

Blunt was always BIG, but now she's GINORMOUS!
The screen grab with those projecting teeth looks fearsome - but that's how she always feeds, this whilst actually being one of the sweetest, most considerate and borderline shy individuals, and getting even mellower as time goes by!
A big, old Shark with a big tummy = a big litter, making her specially valuable.

To be continued!
