Hermit crabs are anomuran decapod crustaceans of the superfamily Paguroidea that have adapted to occupy empty scavenged mollusc shells to protect their fragile exoskeletons. The aquatic hermit crabs almost all marine spend most of their lives underwater as aquatic animals, living in depths of saltwater that range from shallow reefs and shorelines to deep sea bottoms, rarely leaving the water for land.
