Max length : 40.0 cm TL male/unsexed; (Ref. 9276); common length : 30.0 cm TL male/unsexed; (Ref. 9276)
Common around rocky reefs and along continental coasts (Ref. 9276). Feeds on sea urchins, small crustaceans and mollusks, often blowing into sand to uncover prey or turn over urchins (Ref. 5227).
Life cycle and mating behavior
Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae
Females are territorial, solely tending and guarding the eggs (Ref. 116451). Males exhibit polygyny (Ref. 116451).
