description

The appearance of the species is reminiscent of a tadpole with a large head and a body that narrows towards the back. The dorsal and anal fin extend over almost the entire body. In contrast, the caudal fin is very small and the pelvic fins are divided into two parts. In contrast to most of the species in the family, P. bathybius does not have a suction disc. The color is predominantly black with a slight tendency towards dark gray on the back of the body. Up to 25 cm long specimens were registered.

Paraliparis bathybius occurs from the Arctic to the Atlantic south of Greenland and in the Northern European Sea , z. B. near Iceland , around the Faroe Islands and at Bear Island .

The way of life of the species is little explored. It usually resides in cold water layers near the sea floor at a depth of 1,000 to 1,800 meters. The record depth is 4,009 meters. The fish rarely swims in the open sea ( pelagic ). Snails , amphipods and other crustaceans serve as food . In spring, females lay up to 400 eggs.
