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:

Family level detail.
Elongate, eel-like fishes with bodies tapering to a point, long-based low dorsal and anal fins joined to the tail fin, pelvic fins either absent or reduced to 1-2 slender rays usually on the underside of the head; scales small, cycloid. Some species have barbels around the mouth. Brotulas are egg layers and males lack the specialised copulatory organs found in the live-bearing cusk eels of the Family Bythitidae.
