Anyway, mantis shrimp is apparently scourge of the bottomfeeder community. Look no further than this video of one picking on a poor crab. Go ahead and hide underneath that glass, crab. Mantis shrimp is secretly one of the creatures from Starship Troopers. It rips a hole in the glass and then rips a hole in you. Such a shame. Tasty on tasty violence is such an ugly thing.
