Interpreting fin count meristics.
Spines are in Roman numerals and soft rays are in Arabic numerals. Spines and rays that are continuous in one fin are separated by a comma. Fin sections are separated by semicolons.

Detailed descriptions of fin count and other meristics are in:

Order level detail.
A large and highly diverse group of modern bony fishes many of which have a generalized perch like body form. Most have pelvic fins with one spine and 5 rays and the maxillary bone is excluded from the gape of the mouth. Interrelationships of the group are poorly understood and continue to be studied. They inhabit almost all aquatic habitats from high-altitude strams to the deep sea, although most are marine.

Family level detail.
Southern Hemispere reef-dwelling fishes with a high number of dorsal and anal fin elements; dorsal fin, single long-based, deeply-divided; pectoral fin with upper rays branched, lower rays thickened and unbranched; Tail base very narrow, tail forked. Like morwongs, the pelagic young have a distinctive postlarval "paper fish" stage with a very compressed, silvery body. Popular food fishes.

General Description

Body rather long, compressed, moderately deep; tail base narrow; dorsal and anal fins low, dorsal fin deeply notched; tail deeply forked; pectoral fin bluntly pointed, upper rays longest. Silvery grey with greenish brown to brown irregular slender markings above lateral line, margin of pectoral fins and tail black, eye yellowish white. To 65 cm.
