Oyster Clampers are Diminutive, carnivorous oysters that inhabit Cay Bay, the saltmarshes and some bayous. These creatures cannot eat anything larger than Fine in size, but that does not stop them from trying. Oyster Clampers open and close their shells rapidly in order to swim (speed 5 ft., poor) through the water in a mothlike, chaotic fashion. In this manner they accidentally run into swimming creatures. Hazard, CR ½
