Chaves de identificação | Morfologia | Morfometria
Espinhos dorsais (total) : 9; Raios dorsais (total) : 24 - 28; Espinhos anais: 3; Raios anais : 23 - 26. Characterized by having 2 longitudinal bands on the side, one from the hind margin of the eye posteriorly, another from the groove around the caudal peduncle spine anteriorly. Juveniles of less than 5 cm SL lack the anterior band; less than 10 cm SL lack the posterior band. Reaches 24 cm SL.
Often found in large groups in open areas near coral or rock (Ref. 9710). Caught with nets (Ref. 30573). Minimum depth reported taken from Ref. 275.
