The dark ghostshark (Hydrolagus novaezealandiae) is a shortnose chimaera of the family Chimaeridae, found on the continental shelf around the South Island of New Zealand. [1] In June 2018 the New Zealand Department of Conservation classified the dark ghostshark as "Not Threatened" under the New Zealand Threat Classification System. [2]
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 Australian ghostshark is a cartilaginous fish (Chondrichthyes) belonging to the subclass Holocephali (chimaera). Sharks, rays and skates are the other members of the cartilaginous fish group and are grouped under the subclass Elasmobranchii. Alternative names include elephant shark, makorepe, whitefish, plough-nose chimaera, or elephant fish. It is found off southern Australia, including Tasmania, and south of East Cape and Kaipara Harbour in New Zealand, at depths of 0–200 m (0–656 ft). Despite several of its names, it is not a shark, but a member of a closely related group.

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.
The whitetail dogfish is a very rare sleeper shark of the family Somniosidae, found from the eastern Indian Ocean round southern Australia to New Zealand, at depths of between 150 and 500 m. Its length is up to 1.1 m.

Ogilby's ghostshark, also known as the whitefish, is a species of chimaera, native to the waters of Australia and southern Indonesia. It lives near the ocean floor on the continental shelf and continental slope 120–350 m (390–1,150 ft) deep. It reaches a maximum size of 85.0 cm (33.5 in). Reproduction is oviparous and eggs are encased in horny shells. It reaches maturity between 64–70 cm (25–28 in) in length. It is listed as a near-threatened species by the International Union for Conservation of Nature (IUCN) due to steep declines in population in areas affected by trawling.

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.
