Scientific Details

Meristics.
Dorsal fin spines/rays: V-VIII, 25-29
Anal fin spines/rays: III, 12-27
Caudal fin rays: 16-18
Pectoral fin rays: 15-17
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.

Detailed descriptions of fin count and other meristics are in:

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.
Body compressed, often deep, most species with the head almost completely encased in exposed striated bones and very long snout in some. Dorsal fin long-based, continuous, often tall, with a spinous and soft-rayed portion, pectoral fins prominent, upper rays much longer than lower, pelvic fins large with a strong spine. The fin spines are venomous in some or all species.
