Threadfin seasnail

The threadfin seasnail, Rhodichthys regina, is a species of snailfish in the family Liparidae, described by Robert Collett in 1879. It is native to the Arctic Ocean and the northeastern Atlantic Ocean, and it may also be found in the North Pacific. It is a deep-water fish that has been recorded at depths from 1,080 to 2,365 metres, which is about 3,543 to 7,759 feet. The species grows to a standard length of 31 centimetres, or about 12 inches, and the source records that it has no commercial value. Its range across the cold deep waters of the Arctic and the northeastern Atlantic places it among the snailfishes of the high northern seas.
