However, gulper sharks are not always caught intentionally. The deep waters in which the gulper and similar shark species live is difficult to harvest, and longlines are an unspecific form of fishing. Longlines intended for other species can easily catch gulper sharks. [9] Gulper shark that has been caught by a fishing boat
The dumb gulper shark may grow to be 43 in (110 cm) long and has a long, robust head, a long, flattened snout, a large y mouth, and large, green eyes, which help it see at 820 to 1260 ft (250 to 385 m) under water. [2] [3] The body is slender and of moderate size, and is grey to greyish-brown in colour, with a paler underside.
Gulper sharks: 2 20 Gulper sharks are usually deepwater fish. While some, such as the gulper shark Centrophorus granulosus, are found worldwide and fished commercially, others are uncommon and little-known. Their usual prey is other fish; some are known to feed on squid, octopus, and shrimp.
Sharks typically targeted for their liver oil include the school and gulper shark, and the basking shark (pictured). [1] All three of these species are either endangered [2] [3] or critically endangered [4] due to overfishing according to the IUCN, although a legal targeted fishery for basking sharks no longer exists.
The leafscale gulper shark lives near the bottom between 230 and 2,360 metres (750 and 7,740 ft), but usually below 1,000 metres (3,300 ft). Also occurs pelagically in much deeper water. It probably feeds on fish and cephalopods. It is ovoviviparous with a maximum of five young per litter.
The species had previously been identified as a variant of the dumb gulper shark, however was differentiated based on morphology. The western gulper is known from the waters of Western Australia, as well as Indonesia, East Timor, and islands in the Southern Indian Ocean. [2] This shark is classified as "least concern" by the IUCN.
The maximum total length recorded for the gulper shark is 5 ft (150 cm). Gulper shark pups average from 1 to 1.4 ft (30-42 cm) total length at birth. Precise details of the size, age, and growth, such as size at maturity for the gulper shark, are currently unknown. The gulper shark is a slim, relatively long dogfish with two dorsal fins bearing ...
Lowfin gulper sharks live at depths between 300 and 1,400 m. They are ovoviviparous and give birth to up to six pups per litter. They feed on other sharks, bony fish, crabs , and lobsters .
