rock crab

Hard-shelled coastal scavenger

Rock crab refers to several species of crabs found along rocky coastlines, particularly in North America.

They live in crevices and tide pools, emerging to scavenge.

The Atlantic rock crab and Pacific rock crab are both harvested commercially, though they're less prized than Dungeness or blue crabs: We caught some rock crabs off the jetty.
