Mantis Murder Shrimp (slow motion) - Smarter Every Day 121

That's pugilism at its finest.

The first punch is thrown at 1:38 and then shown again in slow motion ten seconds later - then with sound effects.

We then get an explanation of the potential energy storage mechanism at 2:45. That storage mechanism requires a strong material - an organic composite of helicular (sp?) chitin - at 4:29. The variation of the material within the saddle then, is phenomenally complex, varying throughout the surface, depth, and location within the saddle.

Go mantis shrimp!

Interestingly, this is, I think, the only time Destin's sister has been shown.
