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 /pɒliˈmɪksi.ɪfɔːrmz/.[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 TuronianofCanada, from the former Western Interior Seaway.[4]
