How to Distinguish from Similar Species:
Geographical Range: Barkley Sound, Vancouver Island to Isla Cedros, Baja California
Depth Range: Low intertidal to 140 m depth. This species is said to be only subtidal in the Pacific Northwest, but can be found fairly commonly in the low intertidal in southern California.
Habitat: Under rocks and in algal holdfasts
Biology/Natural History: This species is sometimes associated with the purple urchin Strongylocentrotus purpuratus. In aquaria, raise arms and extend tube feet. Capture suspended material on spines and tube feet, pass it down to the mouth via the tube feet. Also may feed by grasping small prey or meat in a loop of the arm and bringing it to the jaws by bending the arm ventrally.
