Tamanho / Peso / Idade
Maturity: Lm ? range ? - ? cm
Max length : 33.0 cm TL macho/indeterminado; (Ref. 2334)
Espinhos dorsais (total) : 8 - 9; Raios dorsais (total) : 22 - 33; Espinhos anais: 2 - 3; Raios anais : 18 - 31; Vértebras: 22. Body varying from light bluish grey to dark brown, without blue lines. Outer part of pectoral fins abruptly white, the demarcation curved such that pale area is broadest on central part of fin. Least depth of caudal peduncle 3.1 to 3.3 times in head length. Maximum standard length about 33 cm (Ref 9808).
Found off steep outer-reef escarpments. May be solitary but most commonly seen in small aggregations feeding on zooplankton well off the bottom.
