Alpheidae (also known as the snapping shrimp, pistol shrimp, or cracker shrimp) is a family of the shrimp infraorder Caridea that is characterized by having an enlarged and highly modified chelae ("claws") on one leg of their first pair, which is used for various purposes. Around half of the species, such as those in the genus Potamalpheops, lack this trait and have been dubbed "non-snapping shrimp".
