It's from a genus called Pachysoma.

You group similar species into a genus.

So this is a mantis shrimp.

And mantis shrimp are called mantis shrimp after the praying mantises, which also have a fast feeding appendage.

And this is a spearing mantis shrimp, or stomatopod.

The earliest members of our lineage, the genus Homo, were darkly pigmented.

These are two shots of a red tide coming on shore here and a bacteria in the genus vibrio, which includes the genus that has cholera in it.

This was how mantis shrimps make these very fast strikes.

I'm going to show you the mantis shrimp approaching the snail.

Like when my son transformed into a praying mantis for Halloween.

So, mantis shrimp come in two varieties there are spearers and smashers.

This is a different species in the same genus but exactly the same foraging behavior.

Maybe I can group species into other categories. And that's where we get the genus from.

Just as in the case of star formation here in galaxy formation, genus length or genus mass are key concept to determine the scale of fluctuations that can actually grow or fragment in the smaller one.

And mantis shrimp are officially the fastest measured feeding strike of any animal system.

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

This is a recording I made of a mantis shrimp that's found off the coast of California.

There are 13 species in the genus, and they have a particular behavior that I think you will find interesting.

So, actually, I started working on what's called the mantis shrimp a few years ago because they make sound.

And what he showed in mantis shrimp is that they use what's called a catch mechanism, or click mechanism.

Now, the other type of mantis shrimp is the smasher stomatopod, and these guys open up snails for a living.

And then he went even beyond that, because even the idea of grouping things into a genus dated back to the ancient Greeks.

So the next and final question was, well, how much force does a mantis shrimp produce if they're able to break open snails?

And while I was struggling to figure out how and why mantis shrimp, or stomatopods, make sound, I started to think about their appendages.

And then we did a series of calculations, and what we were able to show is that these mantis shrimp have to have a spring.

When our First Nations Inuit and Mantis communities are being ravaged by a suicide rate 5 6 times higher than the national average, that's not acceptable.

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 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 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.

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.
