Kurzbeschreibung Bestimmungsschlüssel | Morphologie | Morphometrie

Rückenflossenstacheln (insgesamt) : 9; Rückenflossenweichstrahlen (insgesamt) : 23 - 25; Afterflossenstacheln: 3; Afterflossenweichstrahlen: 22 - 24. Body of adult dark grayish brown; juveniles yellow; posterior to upper end of gill opening is a bright orange horizontal band, with purplish black border. Head and anterior half of body usually abruptly paler than the posterior half. Anterior gill rakers 24-28; posterior 23-27. Large adult males (about 17 cm) with more definite convexity of snout profile.

Inhabit seaward reefs, in areas of bare rock or mixed rubble and sand, from 9 to at least 46 m depth; juveniles inhabit protected bays and lagoons, singly or in small groups in as little as 3 m (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Adults occur singly or in schools and feed on surface film of detritus, diatoms, and fine filamentous algae covering sand and bare rock (Ref. 1602). Rarely poisonous (Ref. 4795).
