Biology/Natural History: Feeds mainly on sponges, or on particulates which stick to mucus on the body surface and are passed to the mouth. Often has a commensal scaleworm, Arctonoe vittata. Small females may brood their young in winter (or the brooders may be a separate species--this is most likely the correct interpretation). Has ocelli at the tips of the rays.

Henricia leviuscula is fairly stiff with only small papulae and tube feet. It seems to rely much more on seawater uptake through the madreporite than does Leptasterias hexactis, another intertidal species of similar size (Ferguson, 1994).
