Sharp-Nosed Crab

Sharp-Nosed Crab (Scyra acutifrons) as seen in our Rocky Shores exhibit.

This crab is named after the unusual shape of its carapace, which has a sharp, snout-like feature at the front and a broad, flat 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 see at first, even in the close-up exhibits in the Aquarium’s Rocky Shores gallery. The sharp-nosed crab is generally a solitary animal that can be found hiding among seaweed, between rocks and on man-made pilings. Their long, delicate-looking pincers allow them to pluck food out of the cracks and crevices in these areas.

Range & Habitat

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.
