Polyipnusとは 意味・読み方・使い方

Polyipnus is an oceanic ray-finned fish genus which belongs in the family Sternoptychidae. This is the largest genus of the marine hatchetfishes (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.
