Cutiscidis, meaning Skin-crab, measure 1-4 inches across.


A remarkable variety of parasite crab, Cutiscidis attached itself to a host's skin and fed from the wound. The Skin-crab's carapace formed a protective scablike cap, to shelter the parasite as it grew. The crab detached only to breed, dropping to the riverbed to locate others of its own kind, after which it would seek a new host.
