Polyipnus

Polyipnus is a genus of oceanic ray-finned fish in the family Sternoptychidae. This is the largest genus of the marine hatchetfishes subfamily Sternoptychinae and indeed of the entire Sternoptychidae. It is not quite as apomorphic as their relatives; it may be that the genus is actually a paraphyletic assemblage of less advanced Sternoptychinae and would need to be split.^[2]

Fossils of this genus show that they have existed at least since the Early Oligocene, about 30 million years ago.^[1]

There are currently 33 recognized species in this genus:
