Special features

The snapping shrimps owes its name to the sound it produces when rapidly closing its claws. The claws produce a shockwave and a loud bang, which can stun unlucky prey. The shrimp shares a burrow with several species of shrimpgoby. The goby provides provides protection since the shrimp has bad sight, and the shrimp in turns does the maintenance on the burrow, providing shelter for the goby. This form of symbiotic relation is called mutualism (both species benefit from the relation).
