The beardfishes consist of a single extant genus , Polymixia , of deep-sea marine ray-finned fish named for their pair of long hyoid barbels . They are classified in their own order Polymixiiformes .[1] But as Nelson says, "few groups have been shifted back and forth as frequently as this one, and they were recently added to Paracanthoptergii".[2] For instance, they have previously been classified as belonging to the Beryciformes . They are of little economic importance.[3]
They are found in tropical and subtropical waters of the Atlantic , Indian and western Pacific Ocean . They are bottom-dwelling fish, found down to about 800 m (2,600 ft ) depth. Most are relatively small fish, although one species, Polymixia berndti , is over 40 cm (16 in ) in length.[3]
The earliest fossils are from the Turonian of Canada , from the former Western Interior Seaway .[4]
