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.

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 family of small to medium-sized eels found in tropical and temperate seas worldwide. All have well-developed pectoral and tail fins, a prominent lateral line and a slit-like gill opening. These bottom-dwelling eels are found in range of habitats from tide pools to the bottom of the deep sea.
