Range of smallfin gulper shark (in blue)

The smallfin gulper shark or endeavour dogfish,[1] (Centrophorus moluccensis) is a medium-sized deepwater dogfish in the family Centrophoridae.

Physical characteristics

The smallfin gulper has no anal fin, two dorsal fins with spines, long free rear tips on pectoral fins, and a deeply notched caudal fin. Its maximum length is 98 cm (39 in).[2]

Distribution

The smallfin gulper is found in the western Indian Ocean off South Africa and Mozambique, and the western Pacific off Honshū, Japan, Indonesia, New Hebrides, New Caledonia, and Australia.[3] The Australian populations are regarded as near threatened in the Eastern[4] and least concern in the Western[5] populations.

Habits and habitat

Smallfin gulpers are common deepwater sharks. They live near the bottom between 130 m (430 ft) and 820 m (2,690 ft). They are ovoviviparous and have two pups per litter. Their diets are primarily bony fish, but also other sharks, molluscs, crustaceans, and even tunicates are consumed.[6]
