The jellynose fishes or tadpole fishes are the small order Ateleopodiformes. This group of ray-finned fish is monotypic, containing a single family Ateleopodidae. It has about a dozen species in four genera, but these enigmatic fishes are in need of taxonomic revision. [1]
The scientific name means "Ateleopus-shaped", from Ateleopus (the type genus) + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek atelēs (ἀτελής, "imperfect") + pous (πούς, "foot") + Latin forma ("external form"), the Greek part in reference to the reduced pectoral and ventral fins of the jellynoses.[2]
