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.
A diverse group of moderately deep-bodied oval fishes with short heads, blunt snouts, a continuous long-based dorsal fin, a concave to forked tail, pelvic fins arising behind the pectoral-fin base and small rough scales. Most are omnivores and often occur in large schools.

General Description
