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 oceanic fishes, with a long, very compressed body, a long-based continuous dorsal fin from the head almost to tail base, long pelvic fins and a large deeply forked tail. Females with a rounded forehead, males with a steep blunt forehead, becoming very steep in adult males.
