An order of actinopterygian (ray-finned) fishes consisting of only one family, Ateleopodidae, known as jellynose fishes. Ateleopodiformes along with the order Stomiiformes constitute a teleost superorder called the Stenopterygii. Jellynose fishes are very distinctive in having a large head and bulbous snout; a long anal fin that unites with a much reduced caudal fin; a dorsal fin placed forward with 3 to 13 rays; a pelvic fin in a jugular position with a single ray in adults; and a largely cartilaginous skeleton (see illustration). Individuals may reach a length of 2 m (6.6 ft) at a depth range of 140–1281 m (called the bathydemersal environment). The family, consisting of 4 genera and 12 species, is represented in the eastern Atlantic, Caribbean Sea, eastern Pacific off Central America, and the Indo-West Pacific.
