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.
A small family of slender, streamlined silvery fishes with a single long-based dorsal fin, the spinous and soft portions joined by a low notch; anal fin short-based, positioned posteriorly; tail deeply forked; jaws with many rows of fine teeth; scales small, covering body and most of head.
