Spine dorsali (totale) : 0; Spine anali: 0.
Body shape (shape guide): other.
Found on the continental shelf and littoral areas (Ref. 247).A sluggish and inactive species that buries itself in sand or mud (Ref. 247). Also found around rocks, heads of submarine canyons, and sometimes near kelp forests (Ref. 247). Feeds on bottom and epibenthic fishes, including croakers, California halibut, and squid (Ref. 247).
