The red rock crab is a compact, brick-red crustacean found in rocky intertidal and shallow subtidal zones across temperate waters. Its robust carapace and sturdy claws make it well-adapted to life among boulders and crevices, where it hunts small invertebrates and algae. Divers exploring rocky reefs and kelp forests often spot these crabs wedged into shelter during the day; they become more active at dusk and during rough seas when surge offers cover.
