ventral fins of the jellynoses.[2]
Description and ecology
Jellynoses are deep-water, bottom-dwelling,
Indopacific, and the Pacific coast of Central America.[3]
Their skeletons are largely
ventral fins that are located behind (not below) the pectoral fins. Dorsal fins tend to be high, with a rather short base (9-13 rays, but in some as few as three); they are placed just behind the head. They have seven branchiostegal rays. The species have a range of sizes, the longest reaching 2 m (6.6 ft).[3] A swim bladder is absent, and some species also lack scales.[4]
Most of the species are poorly known, but the highfin tadpole fish (Guentherus altivelis) is of potential interest for commercial fishing[citation needed].
Systematics
Together with their relatives, the
taxa it would create. In fact, in some treatments, the jellynose fishes are even placed in yet another monotypic superorder, the Ateleopodomorpha.[5]
The Ateleopodidae have also been placed in the
phylogeny of this group of moderately advanced Teleostei is in need of further study.[6]
