| Adults are commonly found in sheltered areas shallower than 5 m. Typical in shallow habitats in coastal mainland areas and seldom on offshore islands. Mainly found under rocks. They feed on a range of benthic invertebrates including ophiuroids, archaeogastropods, trichoptera and errant polychaetes (Ref. 84084). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). They are caught by slurp guns and handnets (Ref. 84086). |
