Adults inhabit shallow rocky areas and tide pools. They hide in empty Strombus gigas shells (Ref. 13628), holes or troughs of rocks, or between algae (Ref. 5981). Herbivorous (Ref. 13442). Feed on invertebrates as juveniles and shift to diet of algae as adults (Ref. 94105). Unusual erectile nuchal crest (Ref. 41019). Oviparous. Eggs are demersal and adhesive (Ref. 205), and are attached to the substrate via a filamentous, adhesive pad or pedestal (Ref. 94114). Larvae are planktonic, often found in shallow, coastal waters (Ref. 94114).
