Biology
Oviparous. Eggs are laid in rocks or in kelp at depths of about 8 or 9 m and are present from March through September. Eggs are more abundant, however, in March and April. Eggs are hatched in about a year; size at hatching is about 18 cm. There may be a `nest"quot; for several females laying eggs but this is not a true nest. A female lays two eggs at a time, for 6 to 12 spawnings. Found on the continental shelf, more commonly on rocky and kelp-covered bottom. Feeds on crustaceans, molluscs (including top shells), small fishes and sea urchins[17641]
