Scientific Details

Meristics.
Dorsal fin spines/rays: III, XXVI-XXVIII, 5-7
Anal fin spines/rays: II, 22-24
Caudal fin rays: (segmented) 11-14
Pectoral fin rays: 13
Ventral fin spines/rays: I, 3
Lateral line: (arched) 17-23 + (straight) 23-30
Gill rakers: 2-3 + 6-8 = 8-10

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.
Mostly small well-camouflaged cryptic fishes with finger-like pelvic fins on the underside of the head and a long-based spinous dorsal fin joined to a short soft-rayed portion. The spinous part begins with several stiff spines, and the soft-rayed part contains up to 6 rays. Head often with orbital and nasal tentacles. They have internal fertilization and give birth to live young.
