Description

Habitat

May be found at depths of 250 to 720 meters.

Ecology: Occurs on or near the seabed on outer continental shelves and upper slopes at 98 to 1,000 m. Eats bony fishes, small dogfish sharks , skates , squid and crustaceans. Ovoviviparous (aplacental viviparous) with one to six (mostly four to six) pups per litter , born at 30 to 45 cm total length (TL ). Matures at around 110 cm (males) to 140 cm (females) with maximum length approximately 170 cm. Although there is limited information on the biology of this species, gulper sharks are considered to have very low rates of population increase and to be very vulnerable to over-exploitation by fisheries. For example, Graham et al. (1997) report documented declines of 99.5% in abundance of Centrophorus species off southern New South Wales, Australia, where this species is known to occur in small numbers. [4].

Notes

Name Status: Accepted Name .

Last scrutiny: Data last modified by FishBase 20-Sep-2000

There has been considerable confusion of this species with many others, e.g. sympatric Centrophorus granulosus or C. uyato (and possibly other species) in many areas. Last and Stevens (1994) identified C. niaukang as C. granulosus (at least in part), and C. granulosus as C. uyato.[4].
