Genus

Common name: Porcelain Crabs

Scientific name: Petrolisthes

Petrolisthes, commonly known as Porcelain Crabs, are a genus of small crustaceans found in a variety of marine environments. They are known for their flat, rounded bodies and two large front claws. Porcelain Crabs are filter feeders, using their feather-like mouthparts to capture plankton from the water. They often inhabit crevices and live under rocks or within coral reefs, where they can maintain a low profile to avoid predators. In the aquarium, they are appreciated for their peaceful nature and their role in consuming excess food and detritus.
