Where they live
Distribution
Widespread in the North Atlantic. Northeast Atlantic from Greenland and Iceland to North Africa, incl. the Azores and Canary Islands. Found in the Northwest Atlantic from Nova Scotia to New Jersey. Unconfirmed reports from the Western Pacific.
Habitat
Predominantly demersal species found on continental slopes from 350–2,213m; 3,750–4,500m on North Atlantic lower rise. Most abundant at depths of 800–1,000m. Segregates by depth and size: larger specimens occurring in depths <600m, mean size range progressively decreases with increasing depth.

Size & biology
- Birth: 12−17cm.
- Matures: female 62cm; male 57cm.
- Max. TL: 94cm.
- Viviparous, litters of 7−18 (avg. 11). Appears to have two peak mating periods: June/July and October.
- Primarily feeds on teleosts, cephalopods and crustaceans; high proportion of the former observed in stomach analyses suggests it may feed in midwater.
Conservation status
IUCN Red List: Global: Data Deficient (2006) Europe: Least Concern (2015) Taken as bycatch in deepwater trawl and longline fisheries across its range. Survey data indicates population is stable in European waters. It is expected to have similar life history and low reproductive characteristics of other deepwater sharks.
Management
Subject to prohibitions under the CFP, RFMO and FNA regulations.
Commercial importance
This species is not generally utilised or traded commercially. Occasionally taken as bycatch and retained in groundfish fisheries in the Eastern Atlantic.
