Maturity: Lm ?  range ? - ? cm Max length : 20.0 cm CW male/unsexed; (Ref. 78486)
Depth range is from intertidal to about 90 m. Max size from male specimen captured off Punta Banda, Baja California (Ref. 78177). Forages on shores protected from wave action. Juveniles and mating pairs occur in the intertidal zone only on nocturnal high tides (Ref. 78483). Buries itself in the substrate during periods of inactivity (Ref. 78491). Excavating predator (Ref. 78493). Most species produce a single brood each winter but may reach up to two or three broods per year and the reproductive life span is about 4 years. The cumulative number of broods produced over the maximum life span is about 4 broods (Ref. 78494). Also Refs. 78494, 111898, 111907 (Ref. 56049).
