Scientific Details

Meristics.

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.
Except for the shore eels of the genus Alabes, most gobiesocids have pelvic fins modified into an obvious sucking disc on the underside of the body. Clingfishes usually have large flattened heads and tapering compressed bodies, with small dorsal and anal fins positioned far back near the tail. They have fin spines and lack scales. Shore eels are elongate, moderately-compressed and eel-like, with long-based dorsal and anal fins united with the tail, and a gill slit on the underside. Their pelvic fins are either minute or absent, and they lack fin spines, pectoral fins and scales.
