An apparently rare deepwater shark, recorded sporadically and usually singly at widely dispersed localities. It may be present at greater depths than are commercially fished, but this is only speculative. It reaches a large size and, although very little is known of its life history, it is likely to be a slow-growing, late-maturing species of low overall productivity. In the Northeast Atlantic there is published qualitative information on a decline in this species over recent decades. At present there is inadequate information to assess the conservation status of this species, however, since it is a known (albeit infrequent) component of fisheries bycatch with probable limiting life history characteristics and likely rare status, the species may well meet the criteria for a threatened category as more information becomes available.

Current Population Trend:Unknown

Habitat and Ecology [top]

Habitat and Ecology:Marine, living on or near the seafloor (as far as is known), on the upper and middle continental slope, mainly in 400 to 900 m (based on relatively few captures) but has also been taken in shallower water. Considered a sluggish shark, but may be capable of short rushes to capture prey (fishes, crustaceans).

Born 30 to 90 cm. Mature ~160 cm M, ~200 cm F. (these sizes are poorly known.) Maximum size ~310 cm. Ovoviviparous with 15 to 25 pups per litter, gestation period and reproductive cycle unknown.

Otherwise, almost nothing is known of the species' biology.

Threats [top]

Major Threat(s): Although rarely encountered, almost certainly an unreported bycatch in several deepwater trawl and line fisheries. Reportedly only used for fishmeal, but the liver oil has been used medicinally in at least South Africa. No population baseline or trends available, apart from a reported reduction in numbers in the north-east Atlantic (Quero and Emmonnet 1993, Quero and Cendrero 1996, Quero 1998).
