Scientific Details

Meristics.
Dorsal fin spines/rays: XVII-XVIII, 25-27
Anal fin spines/rays: III, 8-9
Caudal fin rays: 15
Pectoral fin rays: 13-14
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.

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.
Large robust fishes with small mouths with large ?rubbery? lips, high numbers of spines and rays in dorsal fin, and lower rays in pectoral fins thickened, prolonged and partially detached in some, but thickened and unbranched but not prolonged in others, tail forked. Extremely popular commercial and recreational fishes.
