This crab is named after the unusual shape of its carapace, which has a sharp, snout-like feature at the front and is broad and flat at the rear. The carapace is not spiny like many crabs, but it does have a rough texture which helps facilitate the growth of sponges, tunicates and hydroids that help disguise the animal. As a result of this natural camouflage, the crab may be difficult to spot in its natural environment.
The Sharp-Nosed Crab is generally a solitary animal which can be found hiding among seaweed, between rocks and on human-made pilings. Their long, delicate-looking pincers allow them to pluck food out of the cracks and crevices of these areas.
The Sharp-Nosed Crab can be found in near-shore environments, particular on rocky surfaces or hiding among seaweed up to a depth of 300 feet (91 m). They are common all along the Pacific coast, from Alaska to Baja California.
