In actinopterygians, the pelvic fin consists of two endochondrally-derived bony girdles attached to bony radials. Dermal fin rays (lepidotrichia) are positioned distally from the radials. There are three pairs of muscles each on the dorsal and ventral side of the pelvic fin girdle that abduct and adduct the fin from the body. [citation needed]

The pectoral filaments are greyish-black with white tips and bases. The front part of the pelvic fin is greyish black with the rest of it being coloured white.

The pelvic fin has 4–9 rays, and the stomiiformes possess 5–24 branchiostegal rays. Their scales are cycloid , delicate and easily sloughed off; some are scaleless. The coloration is typically dark brown or black; a few (mostly Gonostomatoidei ) are silver, and photophores (light-producing organs) are common in this order.

The pelvic fin has a single spine and three soft rays. In adult males, the lobe's apex produces a lengthy filament. Caudal fin is lunate or crescent-shaped. Two sharp blades that point forward are on the caudal peduncle. In Juveniles, their blades are not fully grown, as they have a stifling gray-brown tint with black, yellow, and white patterns.
