A rare deepwater shark, known only from the Pacific Ocean. It may be present and more widely dispersed at greater depths than are presently fished, but this is only speculative. It appears to be vulnerable to deepwater trawling and line fishing and, as these fishing activities increase, there is potential for ongoing reduction of what may be a small fragmented population with low resilience to fisheries.

Geographic Range [top]

Range Description:Tropical and temperate waters of the Pacific Ocean, in depths from 10 m to over 400 m (possibly to over 1,500 m). Apparently absent from the Atlantic and Indian Oceans. In Australia, known only from VIC (Last and Stevens 1994) together with a recent record off North Queensland (Mike Cappo, AIMS, pers. comm. May 2003).
Countries occurrence:
Australia (Queensland, Victoria); New Zealand; Palau; Peru; Taiwan, Province of China; United States (California, Hawaiian Is.)
FAO Marine Fishing Areas:
Indian Ocean – eastern; Pacific – eastern central; Pacific – northwest; Pacific – southwest; Pacific – western central

Habitat and Ecology [top]

Habitat and Ecology:Marine, demersal, on the upper and middle continental slope, 10 to 400 m, possibly to 1,500 m. The shallow records are from submarine canyons, in particular Monterey Canyon (California), where there is a notable - and possibly unique - localised abundance. Considered a sluggish shark, but probably capable of swift rushes to capture prey (fishes, crustaceans). Born 40 to 45 cm. Mature 180 to 200 cm (males), 250 to 300 cm (females). Maximum ~400 cm. Ovoviviparous, up to 114 pups per litter have been recorded. Gestation period and reproductive cycle unknown. Life history generally very poorly known.

Threats [top]

Major Threat(s): A bycatch in some deepwater line and trawl fisheries, which will continue as these expand in geographic area and depth range.

Conservation Actions [top]

Conservation Actions: There are currently no conservation measures in place for this species.
