Dont believe me? Google it...
The big ones (6" or greater) can smash thin glass like 10 gallon tanks. However, mantis shrimp that big shouldn't be kept in tanks that small anyway. Keeping them in appropriate tanks takes the danger down to very little. Then there are always acrylic tanks if you'd still worry, and they can't smash through those at all. Truly fascinating critters, and I'd recommend them over a lobster any day.
