Blueband Hermit Crab

Pagurus samuelis

The Blueband Hermit Crab is a small crustacean found along the west coast of North America, from Alaska to Baja California, Mexico. It is most commonly seen in California. Divers can identify this species by its distinctive blue bands on the legs, which may appear white in smaller individuals, and its red antennae. The crab's exoskeleton is typically brown or green, and its legs and carapace are covered in setae. This species is known to inhabit the discarded shells of black turban snails. Blueband Hermit Crabs are nocturnal scavengers, primarily feeding on algae and carrion. They have a particular affinity for the giant kelp Macrocystis pyrifera. In their natural habitat, they are often found in shallow waters, as 90% of recorded sightings occur at depths shallower than 10 meters. During the breeding season, males carry females on their backs, and eggs are produced from May to July. Encounters with the Blueband Hermit Crab are likely to occur in tide pools and coastal waters. They are not currently evaluated for conservation status, and their presence is relatively common in their range. Predators include various fish species such as pile perch and California sheephead.
