Great Whites on Sea Mounts!

Click for detail!

A Great White on a coral reef?

Yes that would be a sea mount in New Caledonia!
The pic was taken in September, 2007 by one Luc Bourdil who if I understand it correctly (Note: I did not, see Luc's explanation in the comments section) was leading a group of divers. Everybody made it up safely, then three very much intrepid (and I would add, very much Gallic) plongeurs went back down to further admire the spectacle, very much proving that GWs are not at all what they are made out to be. And, that Gallic plongeurs are certainly very intrepid and possibly also quite stupid.
More pictures here.

I just got sent the pic by Clinton Duffy.
Clinton is the man who tagged Grim the Fiji tourist and he was also kind enough to send me these tracks of Grim's gallivanting about in Bligh Waters. The yellow ellipses denote the scope of possible position errors and no, he definitely did not traipse around on Vanua Levu like Dakuwaqa!


And there's more that Grim did not do.
It appears pretty clear that he did not visit Plantation Island after all, which must be a great relief to the tourism industry there. And having been given the chance to ask some questions, many of which undoubtedly stupid, Clinton informs me that in his opinion, the NZ GWs who migrate north in winter do not seem to be following the Humpback Whales like I assumed. There is of course temporal overlap but the spatial overlap seems to be, if at all, more or less entirely fortuitous.

In Clinton's words.

While whites definitely visit the same areas the humpbacks do the fit between the movements of these species is not particularly tight.
Some whites are definitely on the grounds at the same time the whales are but some arrive after the whales should have gone and stay on. So while I think there is some link there I don't think the whites are dependent on the humpbacks but I have no doubt they would check them out when they're in the neighbourhood.

I'm also pretty sure that whites from NZ visit Fiji every winter-early summer (July-January), I think its just an artefact of small sample size that only one of the sharks we've tagged so far has been tracked there.

Places you're most likely to encounter them would be on seamounts and in the entrances to deep passes. They've been seen by divers in both habitats in Tonga (2 yrs in a row on the same seamount - Happy Ha'apai Divers) and New Caledonia respectively.

Wow wow wow!
As far as I know, no diver has seen a GW in Fiji yet - or am I mistaken?
Anyway, just imagine if one would pop up on the Shark dive amid the gaggle of Bulls - would that be awesome, or what! :)

Vinaka Clinton - all very very interesting!
Much appreciated indeed!

More Grim News!

Pic: Kina Scollay

Remember Grim the Kiwi tourist?

Now, more details are starting to emerge.
New Zealand's 3News have aired a stellar piece on Clinton Duffy's GW research including a first glimpse at the tracks - and I notice that Grim (4:20 ff in blue) has navigated tantalizingly close to the SRMR! Alas, the embedding feature has not been enabled - but you can watch the program online right here.

Very much looking forward to the published results!
Keep watching this space!

Hat tip: Patric!

Grim News from Fiji!


Wow!
A friend has just sent me a short message Mike, watch out buddy, great whites are out there too! and this link. It is an interesting piece about Grim, a GW that was tagged off Stewart Island last year.

Looks like Grim did pay himself a vacation to Fiji!
As Ozzie Sam did comment about it when I posted about GWs in Fiji last December, Grim went all the way to the Mamanucas and back - and of all places, he obviously decided to take up temporary residence in a lagoon near Plantation Island Resort on Malolo LaiLai! That would be one of the country's most populated family and honeymoon vacation spots!

The channel between the two main islands would be Bligh Water between the islands of Viti Levu and Vanua Levu.
It is named after Capt'n Bligh who negotiated it unharmed (and likely, in a great hurry and with bated breath!) on his epic voyage to Timor and is part of the famous Nai'a Triangle!

Enough said! :)
