The pale ghost shark (Hydrolagus bemisi) is a shortnose chimaera of the family Chimaeridae. It is endemic to New Zealand waters.
This species was first described by Dominique A. Didier in 2002. [1] Although it had been recognised, the description of this species was regarded as being important because of the increase in the commercial fishing of chimaera. [1]
Estimations of growth and age have only been attempted for a quarter of the species known. [2] This species has a medium-sized body with a tapered whip-like tail. [3] Its length is up to 1.12 m. [4] It can be distinguished from H. novaezealandiae and H. homonycteris as it has a pale silvery colour with no patternation or spots. [3] Estimates suggest that they can live between 15 and 22 years, although the lack of data still makes this unreliable. [2]
This species is endemic to New Zealand and can commonly be found from the West Norfolk Ridge to the Campbell Plateau at depths of between 400 and 1100 m. [3]
In June 2018 the New Zealand Department of Conservation classified the pale ghost shark as "Not Threatened" with the qualifier "Conservation Dependent " under the New Zealand Threat Classification System. [5]
Chimaeras are cartilaginous fish in the order Chimaeriformes, known informally as ghost sharks, rat fish, spookfish, or rabbit fish; the last three names are not to be confused with rattails, Opisthoproctidae, or Siganidae, respectively.
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 narrownose chimaera is a longnose chimaera of the family Rhinochimaeridae, the longnose chimaeras, consisting of eight species belonging three genera. This species is found in temperate seas worldwide, at depths between 200 and 3,100 m. Its length is between 1.0 and 1.5 m, including a long, tapering snout and a long, filamentous tail.
The New Zealand catshark 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 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 spotted estuary smooth-hound or rig is a houndshark of the family Triakidae, found on the continental shelves and in estuaries around New Zealand. It is closely related to the gummy shark of Australia. Males can grow up to a length of 125 cm, while females can reach a length of 151 cm.
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 flaccid catshark is a catshark of the family Scyliorhinidae. It is endemic to the waters around New Zealand.
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 carpenter's chimaera, also known as the giant chimaera or the giant purple chimaera, is a species of fish in the family Chimaeridae.
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.
The smallspine spookfish is a species of fish in the family Rhinochimaeridae with a rather disjunct population. Its natural habitat is open seas.

Hydrolagus pallidus is a marine species of fish in the family Chimaeridae found in the Northeast Atlantic Ocean, specifically near Iceland and the Canary Islands. It is commonly known as the pale chimaera or pale ghost shark, although it is not a true shark. Its natural habitat is deepwater seas and near the mid-Atlantic ridge. H. pallidus is found at a depth range of 800 - 3650 m. This species faces a potential threat as bycatch of deepwater trawl fisheries especially as deepwater fisheries operate at greater depths. It has been recognized as distinct from Hydrolagus affinis, its closest relative, since 1990.
Rhinochimaera pacifica, commonly known as the Pacific spookfish, knifenose chimaera, narrownose chimaera, Pacific long-nosed chimaera, or Pinocchiofish, is a species of chimaera in the family Rhinochimaeridae. It lives in various parts of the Pacific Ocean and can be characterized by its long snout.
The black ghostshark, also known as the black chimaera, is a chimaera species within the family Chimaeridae. The species lives off the coasts of Australia and New Zealand, in the southwestern Pacific Ocean, in depths of 500–1,450 m (1,640–4,760 ft). It has a black or dark brown body; males have a total length of 108 cm (43 in). The species is closely related to the abyssal ghostshark. Although it is sometimes caught as a bycatch, it does not have any major threats and is listed as least concern by the International Union for Conservation of Nature (IUCN).
The whitespot ghost shark is a chimaera species in the family Chimaeridae, which lives in parts of the Galápagos Islands in the southeast Pacific Ocean. It lives in waters with steep slopes and boulders and grows to a total length of around 40–50 cm (16–20 in).
The Galápagos ghostshark is a chimaera species in the family Chimaeridae, likely endemic to the Galápagos Islands. It was discovered by John E. McCosker in 1995 and described in 2006, scientifically named in honor of McCosker. This chimaera has a brown compressed, elongate body. The holotype and paratype of the species, both juvenile females, had a total length of 38.1 centimetres (15.0 in) and 22.7 centimetres (8.9 in), respectively. It lives in rocky habitats close to the sea floor, in waters about 395–510 metres (1,296–1,673 ft) deep. It is listed as least concern on the IUCN Red List.
