The flaccid catshark (Apristurus exsanguis) is a catshark of the family Scyliorhinidae. It is endemic to the waters around New Zealand.
This species is found only around New Zealand, although this species' collection records indicate it is widespread and probably continuously distributed over the mid- to lower slope around New Zealand. [2] : 80 The biology of all Apristurus species within the New Zealand Exclusive Economic Zone is very poorly known due to the uncertain taxonomy of the group. [2] : 75 They appear to be most abundant below 1,000 m, and are the only sharks regularly taken in research trawls below 1,200 m on the Chatham Rise. [2] : 80 As relatively little fishing occurs below 1,200 m, a large part of their population may be effectively beyond fishing depths. [3]
The New Zealand Department of Conservation has classified the flaccid catshark as "Data deficient" under the New Zealand Threat Classification System. [4]
The prickly shark is one of the two species of sharks in the family Echinorhinidae, found in the Pacific Ocean over continental and insular shelves and slopes, and in submarine canyons. Bottom-dwelling in nature, it generally inhabits cool waters 100–650 m (330–2,130 ft) deep, but it also frequently enters shallower water in areas such as Monterey Bay off California. This stocky, dark-colored shark grows up to 4.0 m (13.1 ft) long, with two small dorsal fins positioned far back on its body and no anal fin. It is characterized by a dense covering of thorn-like dermal denticles, hence its common name.
John Andrew Frank "Jack" Garrick was a New Zealand ichthyologist. He specialized in elasmobranchs and published many books and articles about shark and ray biology. In 1982, he published a thorough taxonomy on sharks of the genus Carcharhinus, where he identified the smoothtooth blacktip shark as a new species. He is the species authority for several types of sharks, including the New Zealand lanternshark. Garrick was a zoology professor at Victoria University of Wellington, appointed to a personal chair in 1971.
The bareskin dogfish is a little-known, deepwater dogfish shark of the family Etmopteridae. This species is found in the western Pacific from southern Japan to western and southeastern Australia as well as in New Zealand waters.
The pygmy shark, the second-smallest of all the shark species after the dwarf lanternshark, is a squaliform shark of the family Dalatiidae, the only member of the genus Euprotomicrus. Their lengths are up to about 25 cm (10 in) for females and about 22 cm (8.7 in) for males.
The dark ghostshark is a shortnose chimaera of the family Chimaeridae, found on the continental shelf around the South Island of New Zealand. In June 2018 the New Zealand Department of Conservation classified the dark ghostshark as "Not Threatened" under the New Zealand Threat Classification System.
The pale ghost shark is a shortnose chimaera of the family Chimaeridae. It is endemic to New Zealand waters.
The New Zealand catshark, Bythaelurus dawsoni, is a catshark of the family Scyliorhinidae in the order Carcharhiniformes. This species is endemic to in the deep waters around New Zealand. Its length is up to 45 centimetres (18 in). The New Zealand catshark is a small, little-known deep water bottom shark. It is dark brown around the top with a few widely spaced pale spots, and white below. It feeds on bottom-living crustaceans. It is also completely harmless to humans.
The roughskin dogfish is a sleeper shark of the family Somniosidae, found around the world on continental shelves in tropical, subtropical and temperate seas, at depths of between 100 and 1,500 m. It reaches a length of 121 cm.
The blackbelly lanternshark or lucifer shark, Etmopterus lucifer, is a shark of the family Etmopteridae, found around the world in tropical to temperate seas, at depths between 150 and 1,250 meters. Its length is up to 47 centimeters. This species consumes mesopelagic cephalopods, fishes, and crustaceans.
The sherwood dogfish or Sherwood's dogfish is a very rare sleeper shark of the family Somniosidae, found only around New Zealand. The only specimen studied was about 80 cm long.
The slender smooth-hound or gollumshark is a species of ground shark in the family Pseudotriakidae. It is endemic to the waters around New Zealand, where it is usually found close to the bottom over the continental slope at depths of 300–600 m (980–1,970 ft). An extremely slim, plain brownish shark reaching 1.1 m (3.6 ft) in length, the slender smooth-hound can be identified by its broad, flattened head with a long, distinctively bell-shaped snout. Its mouth is angular with short furrows at the corners, and contains a very high number of tooth rows in both jaws. Its two dorsal fins are roughly equal in size.
McMillan's catshark is a catshark of the family Scyliorhinidae, in the order Carcharhiniformes. McMillan's catshark is a small, rare and little-known deepwater shark that is endemic to New Zealand. It is found at depths of 985–1350m on the lower continental slope around New Zealand, on the West Norfolk Ridge and off North Cape. It can grow to a length of 45 cm.
The draughtsboard shark is a species of catshark, and part of the family Scyliorhinidae, so named for its "checkerboard" color pattern of dark blotches. It is endemic to New Zealand, where it is also known as the carpet shark. This shark typically reaches 1 m (3.3 ft) in length and has a thick body with a broad, flattened head and a capacious mouth. Its two dorsal fins are placed far back on the body, with the first much larger than the second.
The white-bodied catshark is a catshark of the family Scyliorhinidae.
The bulldog catshark is a catshark of the family Scyliorhinidae, found in the deep waters of the East China Sea and in the Northwest Pacific. In New Zealand waters it is found at the Reinga Ridge, the West Norfolk Ridge, the Hikurangi Trough and the Chatham Rise as well as on the Campbell Plateau.
The black roughscale catshark is a catshark of the family Scyliorhinidae. It is recorded from the north Atlantic, eastern South Atlantic, in the Indian Ocean and around Australia and New Zealand. The species can be found on continental shelf at depths between 510 and 1,520 m. It can grow up to 90 cm (35 in).
The southern lanternshark is a shark of the family Etmopteridae found in the southeast Pacific between latitudes 29°S and 59°S, at depths of between 220 and 1,460 m. This species has been found off Northland, off the Chatham Islands, on the Campbell Plateau, all in New Zealand waters. Its length is up to 60 cm. Reproduction is ovoviviparous, with 10 to 13 pups in a litter, length at birth about 18 cm. They exhibit bioluminescence.
The roughskin catshark is a species of catshark in the family Scyliorhinidae found near Australia and New Zealand. Its natural habitat is the open seas. This species belongs to a genus of poorly known deep-water catsharks.
The leopard chimaera, Chimaera panthera, is a species of fish in the family Chimaeridae endemic to New Zealand. Its natural habitat is open seas. This species is considered rare and any specimens obtained should be sent to the New Zealand National Fish Collection at the Museum of New Zealand Te Papa Tongarewa.
Garrick's catshark is a species of shark in the family Scyliorhinidae found in the waters of New Zealand. Its natural habitat is the open seas. The new deep-water catshark, Apristurus garricki, is described from the waters of northern New Zealand. It is named in honour of Jack Garrick.
