Nasty little friend

[Sciencin']

I really, really, really like mantis shrimp.
They're so cool.
Not only are they really colorful, but those little boxing-glove hands of theirs can punch as quickly as a 22 caliber bullet, which can produce vacuum bubbles and even light when it hits stuff. They've been known to crack very thick aquarium glass, and can break through the shells of hermit crabs with a single hit. And they have some of the most complex eyes in the animal kingdom. I love these things.
