Biology
Oviparous. Distinct pairing with embrace [17086]. Undergoes yearly migrations to breeding sites. Females lay about 10 to 16 (commonly 10-12) eggs in rock crevices on shallow sheltered reefs at depths of 1-5 m (rarely 20-30 m) during August and September (rarely in July and October). In captivity, females lay 2 eggs a day every 8-17 days. Eggs are hatched after 9-12 months and young then move into nursery areas in bays and estuaries. After the breeding season, males move into deeper waters followed by the females in late September or October. Occurs on the continental shelf (Ref. 75154).
