Polymixiidae
The beardfishes consist of a single extant genus, ''Polymixia'', of deep-sea marine ray-finned fish named for their pair of long hyoid barbel (anatomy), barbels. 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, and they were recently added to Paracanthoptergii". For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance. They are found in tropical and subtropical waters of the Atlantic, Indian Ocean, Indian and western Pacific Ocean. They are bottom-dwelling fish, found down to about depth. Most are relatively small fish, although one species, ''Polymixia berndti'', is over in length.

Berycopsis Pulcher
''Berycopsis'' is an extinct genus of beardfish from the Cretaceous period. Fossils are known from England. It was about long and one of the first members of the Acanthopterygii, the group that includes the present day barracuda, swordfish, seahorses, and flatfish. Like its modern relatives, the first fin rays in the dorsal and anal fins were modified into defensive spines, and the pelvic fins were located close to the pectoral fin Fins are distinctive anatomical features composed of bony spines or rays protruding from the body of a fish. They are covered with skin and joined together either in a webbed fashion, as seen in most bony fish, or similar to a flipper, as ...s.
