Scientific Details

Meristics.
Dorsal fin spines/rays: VI; I, 9
Anal fin spines/rays: II, 9-10
Caudal fin rays: 17
Pectoral fin rays: 13
Ventral fin spines/rays: I, 5

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.

General Description

Body streamlined, very long and slender; snout pointed, lower jaw protruding; mouth large, jaw teeth prominent, including large canines in front of lower jaw; dorsal fins short-based, widely separated; anal fin short-based; pelvic fin origin almost below first dorsal fin; tail forked. Body greenish-grey above, sides silvery fading to white below; fins pale greenish-yellow. To 1.1 m, and at least 5 kg.

Biology

These streamlined voracious predators are solitary or hunt in pairs or in small schools, preying on other fishes and squids. They are often seen patrolling near seagrass and kelp beds, and along reef edges. They are a popular recreational species and a good eating fish.
