She looks like a little crab

(Laughter)

Oh! Good going.

And now I'm not swimming with a nice long stroke,

Now here's a closer view of that community.

What we discovered is whether you look at the leg of a human

There's a fish sitting here.

And one idea comes from lessons from chewing crabs.

But I'm talking about the crabs actually doing the chewing.

And the crabs don't like it at all.

I regard crab as a great delicacy.

He's managed to grab a tip of these worms.

Crab chewing is actually really fascinating.

There are a few people who don't like shrimp, but shrimp, or crabs, or crayfish, are very closely related.

Well it turns out it's these neuromodulators, just like the neuromodulators in that little tiny ganglion in the crabs.

And the same thing's going on over here.

And I don't mean chewing the crabs.

I grew up in Baltimore, and I chew crabs very, very well.

I have only two items here on the slide pink cookies or surimi sticks or, if you like, Campari a lot of our food products that are of a red color are dyed with a natural dye.

Let this be a lesson to you never to lose YOUR temper!'

These are some of the businesses mushrooms, crabs, vegetables, trees, fruits, and this is very interesting Nike ice cream and Nike biscuits this is a village sponsored by Nike.

Most hazardous environment I'd ever seen, and I was back with a guy, lashing the pots down.

And what these shrimp are trying to do is actually harvest the bacteria from the backs of these animals.

And we also found this spectacular yeti crab that lives near boiling hot hydrothermal vents at Easter Island.

And I'll never forget, up in the Bering Sea, I was on a crab boat with the Deadliest Catch guys which I also work on in the first season.

I shared my nursery with other embryos and juveniles, from clams and crabs to sea urchins and anemones.

Do we really understand that principle of tuning? The answer is, yes!

The surimi sticks of crabmeat, or is being sold as crab meat, is white fish that's being dyed with cochineal.

Wherever there were people and you can see boats with the women, selling things here's the floating market selling bananas and crabs and also contraceptives wherever you find people, you'll find contraceptives in Thailand.

And living amongst the tangle of tube worms is an entire community of animals shrimp, fish, lobsters, crab, clams and swarms of arthropods that are playing that dangerous game between over here is scalding hot and freezing cold.

We did that by putting these artificial spines on crabs, as you see here, and then we tested them.

And they would see a coral head, maybe 10 feet away, and start moving over toward that coral head.

'I went to the Classics master, though.

These long filaments that you see on the back of the crab are actually created by the product of that bacteria.

And they're not concepts that I've come up with, but concepts that have been proposed by others in the past.

72 percent of the population has such scars, but most don't shed the gear, things like lobster traps and crab pots.

This veliger larvae will turn into a snail this zoea, into a crab and this planula, into a clytia jelly.

And where they have a problem with this kind of mesh, because they don't have spines.

Well, a human, one of your legs works like two legs of a trotting dog, or works like three legs, together as one, of a trotting insect, or four legs as one of a trotting crab.

The amazing thing about this is that it's controlled by a really tiny set of neurons, about two dozen neurons that can produce a vast variety of different motor patterns, and the reason it can do this is that this little tiny ganglion in the crab is actually inundated by many, many neuromodulators.

But he looked at me, and he said, Son he's my age, by the way, he calls me son, I love that he says, Son, I'm a captain of a crab boat.

So I really think that, as we learn more, it's going to turn out that the whole fly brain is just like a large version of this stomatogastric ganglion, and that's one of the reasons why it can do so much with so few neurons.

They're tuned such that they easily collapse in one direction to pull the leg out from debris, but they're stiff in the other direction so they capture disparities in the surface.
