----------- The beardfishes are a small family (Polymixiidae) of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. They have little economic importance.[1] They are found in tropical and subtropical waters of the Atlantic, Indian and western Pacific Ocean. The are bottom-dwelling fish, found down to about 800 metres (2,600 ft) depth. Most are relatively small fish, although one species is over 40 centimetres (16 in) in length.[1] Classification Ten species of the single extant genus Polymixia are known,[2] along with several fossil genera. At present they are classified in their own order Polymixiiformes,[2] but as Nelson says, "few groups have been shifted back and forth as frequently as this one".[3] For instance, they have previously been classified as belonging to the Beryciformes.
