Scientific Details



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.
Mostly coastal fishes with rather deep compressed bodies, a small mouth broadly separated from the eye, a single long-based dorsal fin with strong spines and soft rays, long pointed pectoral fins and rather large, firmly attached scales. Jaws with two forms of teeth, canines or incisors at the front and rounded or flattened molars in the rear.
