Corystes cassivelaunus, the masked crab, helmet crab or sand crab,[1] is a burrowing crab of the North Atlantic and North Sea from Portugal to Norway, which also occurs in the Mediterranean Sea.[2] It may grow up to 4 centimetres or 1.6 inches long (carapace length).[1] The name "masked crab" derives from the patterns on the carapace which resemble a human face (a case of pareidolia), in a similar manner to heikegani.[3] It is the only species in the genus Corystes.[4]
C. cassivelaunus lives buried in sandy substrates, where it feeds on the infaunal invertebrates such as polychaete worms and bivalve molluscs.[1] It uses its two antennae to form a breathing tube that allows oxygenated water down into the substrate.[5][6] The chelipeds of males are much longer than the body, while those of females are only about as long as the carapace.[7]
