Chimaeras are cartilaginous fish in the order Chimaeriformes. They are related to the sharks and rays, and are sometimes called ghost sharks, ratfish (not to be confused with the rattails), or rabbitfishes. The dark ghost shark, Hydrolagus novaezealandiae, is a shortnose chimaera of the family Chimaeridae, found on the continental shelf around the South Island of New Zealand at depths of between 25 and 950 m. Its length is up to nearly 90 cm, not including the filamentous tail up to a third of the body length. The dark ghost shark has a conical snout and an elongated tapering body surmounted by a triangular first dorsal and a long low second dorsal fin. The mouth is small and located well back beneath the snout. The coloration is dark grey above with a mottled pattern of distinct silver-white markings, and pale silver-grey beneath. Their diet is crustaceans, shellfish, worms and small fish.
