It is particularly common in the intertidal zone, an area that is exposed to air during low tide and submerged during high tide. The species is typically found in shallow waters, with a depth range of up to 20 meters. Paguristes parvus is a common inhabitant of the neritic zone, the region of the ocean that extends from the shoreline to the edge of the continental shelf.
