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 mersitics are in:

Order level detail.
Body usually very long, slender, with long-based dorsal and anal fins continuous with the tail fin (if present) in all but one species. All species lack pelvic fins, and some groups lack pectoral fins. Scales are usually absent, or if present, are embedded in skin. All species pass through a pelagic, ribbon- or leaf-like larval stage called a leptocephalus larva.

Family level detail.
A large and diverse group of small to large bottom-dwelling eels, mostly found on tropical and subtropical reefs. Their dorsal and anal fins are continuous with the tail and they lack scales, and pectoral fins. They have a reduced lateral line, pore-like gill openings and most have well-developed teeth and often intricate colour patterns.
