Scientific Details

Meristics.
Dorsal fin spines/rays: 16-20 (pairs of disc laminae); 20-27
Anal fin spines/rays: 20-25
Caudal fin rays: 17
Pectoral fin rays: 26-30
Ventral fin spines/rays: I, 5
Lateral line: 28-37

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.
A small family of slender cylindrical fishes with the first dorsal fin modified into an oval sucking disc, used to attach to a host such as larger fishes, turtles and whales.
