beardfish中文什么意思
百科释义
The beardfishes consist of a single extant genus (Polymixia) in a small family (Polymixiidae) of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. At present they are classified in their own order Polymixiiformes, but as Nelson says, "few groups have been shifted back and forth as frequently as this one".
