Little known fact: the Mantis Shrimp is also the most delicious crustacean EVAR. Like a cross between lobster and crab and baby unicorn… OMFG good. Violent little buggers too… I got lucky that I was handling it carefully, because I didn’t know about its amazing punching powers at the time.

Another fun fact: they can see and selectively reflect radial polarized light… only known critter to use it… until we adopted that for 3D movies recently, using clockwise & counterclockwise instead of horizontal & vertical for the different eye / lens filters.
