A Smashing Club
The raptorial appendage is a club which it swings with spring-loaded force to break snails and crab shells. Like the peacock mantis shrimp, it strikes in a fraction of a second. See Peacock Mantis Shrimp.
Territorial Fights
Mantis shrimp fight over burrows with ritualized displays and strikes onto each other's armored tails. Individuals recognize rivals and avoid repeated fights.
Eyes and Vision
They have complex eyes with many types of receptors. See Spottail Mantis Shrimp.
