The Randall’s Pistol Shrimp, also known as the Red Banded Snapping Shrimp, is easily identified by the characteristic red and white horizontal bands running the full length of its body, including the claws. The legs, however, are generally white or yellow. Like all snapping shrimps, it has one large claw that can be used to deter predators or disable potential prey. The larger claw creates a loud popping sound when opening and closing by expelling water. The expelled water can kill or stun the shrimp’s prey.
