    PZ, you realise you’re just playing into Ken Ham’s deadly rhetorical clutches with this.

    Sharks developed forcefields to defend themselves against the ravenous hordes. Next stop, lasers.

    Oh. Just to display mt ignorance of this field of study, i thought it was the beginnings of a sharknado.

    I love the directional aspect. It’s a flow field, not just a force field.

    We fish are amazing.

  5. 5

    Now that’s fascinating. I really want to see it in motion.

  6. 6

    Smart fishies.

    Do bully fish force today fish into dares? “I dare you to touch the dorsal fin of the shark? Just curious….

    I don’t usually comment on the MMM since they are all beautiful or cool but this one, wow.

    Menyambal, I was thinking the same thing. Fish avoiding predators are a tensor field.

    whoah….mind blown.

    If magnets emit lines of magnetic force, what do sharks emit?

    @2: because everything should have a hot meal?

    I was actually watching something like this on Sunday evening on the BBC (called ‘The Great Barrier Reef: Nature’s Miracle’, and can be found on iPlayer for those that can access it). It was about the Great Barrier Reef, and included footage of lemon sharks hunting, which looks a lot like this. Very cool ^.^
