Descrição breve
Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 21; Raios dorsais moles (total) : 25 - 29; Espinhos anais: 1; Raios anais moles: 24 - 26; Vértebras: 59 - 60. Adults with 5 broad blackish bands on body (Ref. 559).
Body shape (shape guide): fusiform / normal.
This species is found at the demersal zone and near surface over reefs and hard bottoms from intertidal zone to about 2.360 ft (719.8 m). It is preyed upon by other fishes, sea birds and marine mammals (Ref 114183).
Spawns twice a year (Ref. 28499). Eggs are deposited in rock crevices and are guarded by the male who continuously fans the egg mass with his pectoral fin until hatching (Ref. 28499), which occurs after 40-45 days (Ref. 27369).
