Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Espinhos dorsais (total) : 6 - 7; Raios dorsais (total) : 39 - 43; Espinhos anais: 3; Raios anais : 31 - 37. Strongly compressed discoid body. Tubular snout with a small mouth containing numerous elongate bristle-like teeth. Dorsal spines elongated into a whip-like filament.

Inhabit turbid inner lagoons, reef flats, and clear seaward rocky and coral reefs (Ref. 1602, 48637). Benthopelagic (Ref. 58302). Generally encountered in small groups of 2 or 3 individuals (Ref. 9267). Adults occur singly, in pairs and occasionally are seen in large schools (Ref. 48637). Feed on small encrusting animals (Ref. 6113). Size of metamorphosis from postlarva to juvenile is 7.5 cm (Ref. 9267). The long pelagic larval stage is the reason for the wide distribution and strong colouration that shows no geographical variation (Ref. 48637). Popular aquarium fish but rarely survives in tanks (Ref. 1602). Minimum depth reported taken from Ref. 128797.
