Description

The black ruff is a slender, dark oceanic fish of the family Centrolophidae reaching about 1.5 metres. The brown-black body has large eyes, thick lips and a long, low dorsal fin running along much of the back. The species is a wandering deep-water inhabitant of temperate oceans worldwide, including the north-eastern Atlantic and the Mediterranean, sometimes straying into the North Sea. In open water above the continental slope it hunts squid, fish and gelatinous plankton such as jellyfish. Juveniles live higher in the water column and move to deeper water with age. Because of its wandering, oceanic lifestyle it is rarely observed and has no targeted fishery importance.
