Put a crab inside it.

Crab plover Order CharadriiformesFamily DromadidaeThe crab plover is related to the waders, but is the only member of its family.

I have a hermit crab named Hawthorne, who doesn't get a lot of respect as a hermit crab, so he kind of wishes he were a great white shark.

He is best known for discovering the Crab Nebula in 1731.

My neighbor served the most delicious crab dip at her party last night.

'More Glorious than the Sun' by Hexie Farm's Crazy Crab for China Digital Times.

And mantis shrimp are officially the fastest measured feeding strike of any animal system. So our first surprise.

The pulsar at the heart of the Crab nebula, for example, rotates 30 times per second.

The , Macrocheira kaempferi , is a species of marine crab that lives in the waters around Japan.

And mantis shrimp are called mantis shrimp after the praying mantises, which also have a fast feeding appendage. And I started to think, well, maybe it will be interesting, while listening to their sounds, to figure out how these animals generate very fast feeding strikes.

It was a byproduct of commercial gillnetting, with no commercial appeal and was used only for crab bait.

Now, this is pattern thinking. That praying mantis is made from a single sheet of paper no scotch tape, no cuts.

So this is a mantis shrimp. There are the eyes up here, and there's that raptorial appendage, and there's the heel.

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

They even use names of you know, use the name of this world changing battle between the grass mud horse and the river crab.

And if folding a single praying mantis from a single uncut square wasn't interesting enough, then you could do two praying mantises from a single uncut square.

And to give you a simple example here as to what we actually fed these customers, there's a bale of hay there and some crab apples.

So this is a potent force in fluid systems, and just to sort of take it one step further, I'm going to show you the mantis shrimp approaching the snail.

Biologist Sheila Patek talks about her work measuring the feeding strike of the mantis shrimp, one of the fastest movements in the animal world, using video cameras recording at 20,000 frames per second.

So, a quick strike like that. And if we slow it down a bit, this is the mantis shrimp the same species recorded at 1,000 frames a second, played back at 15 frames per second.

And if any of you ever have a chance, backstage of the National Museum of Natural History is one of the world's best collections of preserved mantis shrimp. And what this is serious business for me.

So, this what I saw, on every single mantis shrimp limb, whether it's a spearer or a smasher, is a beautiful saddle shaped structure right on the top surface of the limb. And you can see it right here.

Now, I said all these animals are sort of working like pogo sticks they're bouncing along as they move. And you can see that in this ghost crab, from the beaches of Panama and North Carolina.

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.

What we discovered is whether you look at the leg of a human like Richard, or a cockroach, or a crab, or a kangaroo, the relative leg stiffness of that spring is the same for everything we've seen so far.

Then he meets the yeti crab, the famous vampire squid elusive, hard to find and the Dumbo octopus, which looks so much like a cartoon in real life that really didn't have to change a thing when I drew it.

And I don't know whether they actually saw crab in it, or imagined that one might be, but whatever the case, they would leap off the bottom and go through the water and land right on top of this coral head, and then the web between the arms would completely engulf the coral head, and they would fish out, swim for crabs.
