Porcelain crab [SEP] Biogeography and ecology
Porcelain crabs live in all the world's oceans, except the Arctic Ocean and the Antarctic. They are common under rocks, and can often be found and observed on rocky beaches and shorelines, startled creatures scurrying away when a stone is lifted. They feed by combing plankton and other organic particles from the water using long setae (feathery hair- or bristle-like structures) on the mouthparts. Some of the common species of porcelain crabs in the Caribbean Sea are "Petrolisthes quadratus", found in large numbers under rocks in the intertidal, and the red-and-white polka-dotted "Porcellana sayana", which lives commensally within the shells inhabited by large hermit crabs.
