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.
Long, silvery, streamlined surface-dwelling fishes. Species within the group have a variety of jaw lengths and shapes, and during development, many species go through a half-beak stage where the lower jaw is elongated. The single dorsal fin and the anal fin are usually far back on the body and the pelvic fins are abdominal. All lack fin spines and the lateral line runs along the lower surface of the body.
Most species are counter-shaded to avoid being seen by predators and prey. They are usually dark greenish to bluish above and silvery white on the sides and belly, sometimes with a dusky or darker stripe along their sides.

Family level detail.
A group of slender elongate surface-dwelling fishes with a short, triangular upper jaw and long lower jaw with a fleshy tip, short-based dorsal and anal fins set far back on the body and pectoral fins set high on the body.
