Project Description

This crab has a small forward facing point on its head like the horn of a rhinoceros after which it is named.  The rhinoceros crab (Rhinolithodes wosnessenskii) also has a triangular carapace with a deep semicircular groove on the dorsal surface.  The legs of the crab are covered in hair, which tends to hide their shape, making this animal difficult to see on rocks covered with life.  The rhinoceros crab has a carapace width of about 3 inches (7.6 cm), and a range from central Alaska to northern California.
