Status in World Register of Marine Species:
Accepted name: Centrolophus niger (Gmelin, 1789) (updated 2009-06-25)

Diagnosis: elongate body, small head with pores in the naked skin. Large mouth with no teeth on palate. Single dorsal fin originating just behind pectoral fin base and with about 5 weak spines graduating to the rays. D IV-V + 32-37; A III + 20-23; P 19-22. Scales very small, 160-230 in the lateral line. Colour: ranges from russet through chocolate brown, even to dark bluish; young have dark vertical bands. Size: to 150 cm SL.

Habitat: epi- or mesopelagic, offshore in temperate waters; occasionally taken over the continental shelf in bottom trawls. Behaviour: may form small schools at times. Young in the surface layers, adults deeper. Does not typically associate with floating objects. Food: appears to feed on whatever is available, with small fish, squid, large pelagic crustaceans, and other plankton being found in stomachs. Young may eat medusae, but not preferentially. Reproduction: spawning from autumn into winter. Growth of young very rapid (in 5 months a Mediterranean specimen increased from 2 to 17 cm). Allometry not marked. Jaw teeth increase in number with growth.

Distribution: temperate waters of the North Atlantic western Mediterranean and Adriatic Sea. A virtually indistinguishable form is widespread in the southern hemisphere. To date, young are known only from the eastern Atlantic and western Mediterranean.
