Biologia     Glossario (es. epibenthic)

Found close to rocks near patches of sand and in tide pools. Dart into sand when disturbed and sleep at night buried in sand with head protruding. Feed on gastropods, small crustaceans and has been observed to pick ectoparasites from other fishes (Ref. 9311). Each individual functions first as female but changes to a male at length of about 30 cm. Pelagic spawners (Ref. 56049).
