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.

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.
Streamlined, active-swimming fishes, with fine smooth scales, a relatively short-based spinous first dorsal fin, a long-based soft-rayed second dorsal fin, a narrow tail base and a deeply forked tail; usually a detached pair of short spines before the anal fin. While adults usually inhabit coastal or near shore waters, juveniles are often far from land around floating debris or large planktonic invertebrates such as jellyfish. Many are highly valued gamefish and some are commercially important.

General Description

Body compressed, elongate, oval, tail base slender; pectoral fins short, pointed; a low fleshy lateral keel on the tail base (keel poorly developed in adults). Dark blue above, silvery below with broad yellowish stripe on midside. To 2.5 m.

Biology

This species is found in large schools, especially around coastal reefs: adults usually occur around deep reefs and offshore islands, smaller fishes generally closer to coast. They feed on fish and squid, and are highly-prized by recreational anglers.

Habitat

Cool tropical to temperate waters, around rocky reefs; enters bays, ocngregating around channel markers and drop-offs, in depths of 0-50 m.

Reefs
