Etymology: Centroscymnus: centr[um] (L.), prickle or sharp point, referring to spines on both dorsal fins; scymnus, an ancient name for some kind of shark, derived from a Greek word meaning young animal, cub or whelp. (See ETYFish); coelolepis: coelo-, from koilos (Gr.), hollow; lepis (Gr.), scale, referring to its concave skin denticles. (See ETYFish).

Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 2; Anal spines: 0. Dorsal fins with very small spines, very short snout, lanceolate upper teeth and bladelike lower teeth with short, oblique cusps, stocky body that does not taper abruptly from pectoral region, very large lateral trunk denticles with smooth, circular, acuspidate crowns in adults and subadults (Ref. 247). Uniformly golden brown to dark brown in color (Ref. 6871).

Found on continental slopes and abyssal plains (Ref. 6871). Feeds mainly on fish (including sharks) and cephalopods (Ref. 6871), also gastropods and cetacean meat (Ref. 5578). Ovoviviparous (Ref. 205), with 13 to 29 young per litter, born at 27-31 cm (Ref. 26346); 32-35 cm TL in North Atlantic (Ref. 98315). Utilized as fishmeal, dried and salted for human consumption, or as a source of squalene (Ref. 6871).
