The oyster crab (Zaops ostreus) is a small, whitish or translucent crab in the family Pinnotheridae.
It is less than half an inch across, and lives inside the gills of an oyster or a clam.[3] It uses the oyster for protection and lives on the food that the oyster gets for itself. It is found in oysters in the North Atlantic Ocean.[3]
Zaops ostreus is found along the eastern seaboards of North America and South America, from Massachusetts to Brazil, including the Gulf of Mexico and the Caribbean Sea.[4]
