Elasmobranchii (sharks and rays) > Squaliformes
(Sleeper and dogfish sharks) > Etmopteridae
Etymology: Centroscyllium: Greek, kentron = sting + Greek, skylla = a kind of shark (Ref. 45335).
Environment: milieu / climate zone / depth range / distribution range
Marine; bathydemersal, usually 180 - 2250 m (Ref. 117245). Deep-water; 1°C - 5°C (Ref. 117245); 68°N - 57°S, 99°W - 120°E (Ref. 55215)
Northwest Atlantic: South Baffin Island and Greenland to Virginia, USA and possibly the Gulf of Mexico. Eastern Atlantic: Iceland along Atlantic slope to Senegal; Guinea to Sierra Leone; Namibia to Quoin Point, South Africa (Ref. 5578). Southwest Atlantic: Uruguay to Argentina (Ref. 58839).
Length at first maturity / Size / Weight / Age
Maturity: Lm 64.0, range 58 - 70 cm
Max length : 107 cm TL male/unsexed; (Ref. ); common length : 84.0 cm TL male/unsexed; (Ref. 247); common length :70 cm TL (female)
Adults uniformly blackish; fins of juveniles with white margins (Ref. 6577).
Found on the outermost continental shelves and upper slopes, mostly below 275 m (Ref. 247). Epibenthic-pelagic (Ref. 58426). At high latitudes, may move up to the surface especially during the winter (Ref. 247). Bottom water temp. Are from 3.5 to 4.5°C, but sometimes down to 1°C. Segregation by sex and size as well as by movement into shallower water and by increase in school size is sometimes seen. Feeds on crustaceans, cephalopods, jellyfish and small fishes. Ovoviviparous (Ref. 205), with at least 14 pups in a litter (Ref. 247). Has luminescent organs in skin. May reach 107 cm.
