Maturidade: Lm ? range ? - ? cm
Max length : 90.0 cm FL macho/indeterminado; (Ref. 1602); idade máx. registrada: 31 anos (Ref. 52229)
Espinhos dorsais (total) : 4 - 5; Raios dorsais (total) : 28 - 30; Espinhos anais: 2; Raios anais : 27 - 28. Distinctive humped back; horn only in adult males. A few scattered small dark-edged pale spots on postorbital head and body above pectoral fins. No white margin posteriorly on caudal fin. Profile of snout from mouth to eye strongly sloping, forming an angle of about 40° to horizontal axis of body (Ref 9808).
Body shape (shape guide): fusiform / normal.
Inhabits deep coastal, usually in small groups but occasionally in large schools (Ref. 48637). Sometimes solitary (Ref. 90102). An uncommon species found in seaward reef slopes (Ref. 9710, 48637), also along rocky shores (Ref. 30573). Feeds on benthic algae (Ref. 30573). Caught with nets (Ref. 30573).
