pistol shrimp

The pistol shrimp, also known as a snapping shrimp, is a type of small shrimp belonging to the suborder Natantia. These crustaceans are characterized by their semitransparent bodies and flexible abdomens. The most distinctive feature of the pistol shrimp is its greatly enlarged claw, or chela. By rapidly snapping this claw shut, the shrimp creates a cavitation bubble that collapses with a loud snapping sound. This snap can stun or even kill small prey, which the shrimp then consumes. Pistol shrimp typically grow to about 3.5 cm (1.4 inches) in length. They inhabit all oceans and can be found in both shallow and deep waters.123
