Pinnotheridae is a family of tiny soft-bodied crabs that live commensally in the mantles of certain bivalve molluscs and the occasional large gastropod mollusc species in genera such as Strombus and Haliotis . Tunicotheres moseri is commensal with a tunicate.[1] The earliest fossils attributable to the Pinnotheridae date from the Danian.[2]
