Scientific Details

Meristics.
Dorsal fin spines/rays: XI, 10-12
Anal fin spines/rays: III, 10-11
Caudal fin rays: 17
Pectoral fin rays: 18-23
Ventral fin spines/rays: I, 5
Lateral line: 34-41

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 small family of brightly-colooured planktivorous fishes generally found on deeper reefs. They are closely related to serranids, and differ in having the lateral line high following the dorsal profile just below the dorsal fin, dorsal and anal fins with spines and rays progressively increasing in length, and row of modified scales with pits and grooves along the middle of the side.
