description Umbrella Crab Overview
The umbrella crab is a lithodid crab of the North Pacific coast. Its broad, domed carapace extends over the sides of the body and hides much of the walking legs, producing the umbrella-like outline that gives the animal its common name. It is a marine crab of rocky coastal habitats and is of interest to field observers because its unusual shell shape makes it identifiable even when the appendages are tucked beneath the body.
