More Info


Distribution

Murion Islands to the offshore reefs of north Western Australia, the Arafura Sea, Northern Territory, and the Great Barrier Reef, Queensland to northern New South Wales. Elsewhere the species is circumglobal in tropical and subtropical seas. Juveniles often inhabit near-shore surface waters, often sheltering below jellyfishes, while the adults are probably benthopelagic.

Features

Dorsal fin X-XI + I-II, 18-22; Anal fin II, 21-23; Pectoral fin 18-20; Lateral line scales 55-62.
Body firm, oval, deep (depth > 40% of SL), juveniles deeper-bodied, compressed; eye large, usually surrounded by a fatty ring; operculum thin, with 2 short spines. Mouth small, teeth in upper jaw small, conical, widely-spaced in a single row; lower jaw of adults with long, knife-like close-set teeth; teeth present on vomer, palatines, and base of gill arches, absent from tongue. 
Two barely separate dorsal fins, originating before, or, in large specimens, over pectoral-fin origin; in pectoral fin of adults long, wing-like, with oblique bases, somewhat pointed (short, rounded in juvenile); anal fin spines weak; pelvic-fin origin below pectoral-fin base, attached to abdomen, able to be folded into a groove; Caudal fin of adult deeply forked, tips rounded in juvenile.
Branched mucous canal system beneath skin along midsides; scales small, very thin, cover bases of median fins, on top of head in a narrow band, reach only to between eyes; lateral line high on body.
