Shark-mediated Trophic Cascade in Fiji - Paper!

Reeftop predators: Blacktip Reefie and Bluefin Trevallies - great pic by Allen!

Nice!

Read this.
It illustrates how Reef Sharks influence the behavior of seaweed grazers and consequently, consistently influence the size and distribution of seaweed on the back reef of Votua, i.e. right in front of the iconic Eco Café, home of Fiji's very best wood-fired pizza, friendliest service and most beautiful smiles.

Well done Doug and Mark.
I must really say that this is science at its best, with observations leading to questions and then a proper hypothesis that is being rigorously tested, exactly as it should be. What I also like, is that the authors refrain from unduly exaggerating and generalizing the role (and trophic ranking!) of Reef Sharks but instead attribute the cascading effects to the specific situation alone - again exactly as it should be.

Required reading.
Enjoy!

Bird-eating GTs - Video!

This is beyond awesome.
Latest since that paper, I knew that those GTs are totally badass - but seeing this, along with the unbelievably spectacular footage and the awesome editing simply leaves me in total awe!
And yes this would obviously be the BBC - who else!

H/T Serena - enjoy!

Shark Dive Videos!

The only acceptable Shark soup indeed!

Stunning - and captured whilst following our normal procedures!
Enjoy!





PS: And by the way.
Turns out that that small male (!) Maskray at 6:37ff in the first video may well be a species of interest!
I've now spent the better part of the day conversing with prominent Elasmo taxonomists - and the consensus is that this may be something akin to, but quite possibly different from the recently described N. trigonoides (and here) in the Neotrygon species complex.
 
With that in mind, should you have any pics or video of Bluespotted Maskrays from Fiji, please do forward them to the excellent people of Shark Search Indopacific.
Thank you!

Thank you so much Melinda!

This is really, really nice.
Melinda is a repeat visitor - and it really shows as she understands, and has pretty much nailed what we do, and why.
Much appreciated, really!

Enjoy!

And Yannis most certainly agrees.
