Dorsal spines: 11-12; Dorsal rays: 15-16; Anal spines: 3; Anal rays: 11-12.
A compressed, deep-bodied fish. Soft dorsal and anal fins rounded and symmetrical so that with the tail they can appear to be a single three-lobed fin. Triangular head projecting from body.

Small scales extend onto the bases of dorsal, anal and caudal fins.

Size:

Maturity: Lm unknown. Range unknown. Max Length: 110cm TL. Commonly to 80cm TL. 


Habitat and Ecology:

Pelagic and coastal species (depth 0-70m). A sluggish offshore fish that often floats on its side near the surface in the company of floating objects and occasionally drifts into shallow water. Juvenile may occur in floating Sargassum and mimic a floating leaf. Small juveniles common in mangrove areas, where their black and yellow coloration inhabit a floating on their sides makes them look like a floating mangrove leaf. Feeds on benthic crustaceans and small fish. 


Fishery Status:

This species is not protected or subject to fishery regulations. It is caught in seine and gill nets and with hook and line. It is a rare component of the artisanal catch.

It can however regularly be seen for sale at the market in its salted form. This appears to be reaching the market from the industrial purse seine fishery, where it is perhaps vulnerable to the FAD fishery.
