P. pilosimanus occurs in the western Atlantic Ocean and is most common at depths of 1,000 meters. It is part of a complex of related deep water hermit crabs. P. pilosimanus, along with its sister species P. scaber, has a symbiotic relationship with zoanthid polyps, an order of Anthozoans related to the anemones. It is from their symbiosis with zoanthids that P. pilosimanus is also called the Anemone Crab.
