Remarks | Habitat consists of large boulders (1-2 m in diameter) on a steep slope, with some sand in between the stones, and no bivalve shell accumulations or other rubble present; habitat characterized by currents, low sedimentation rates, coarse sediment and high visibility; these habitats are generally found at capes along the coast; presence of sand mandatory because species creates refuges by removing sand at foot of large stones; dives for cover when approached; most common at depth between 10 and 20 m; strong site fidelity and small home range (2 m diameter); ingests sediment and spits it out through mouth (Ref. 74422). |
