Chimaeras live in temperate ocean floors, with some species inhabiting depths exceeding 2,000 m (6,600 ft), [8] with relatively few modern species regularly inhabiting shallow water. Exceptions include the members of the genus Callorhinchus , the rabbit fish and the spotted ratfish , which locally or periodically can be found at shallower depths.

Studies so far have shown the sequence and the gene order are more similar between human and elephant shark genomes than between human and teleost fish genomes (pufferfish and zebrafish), though humans are more closely related to teleost fishes than to the Australian ghostshark. The Elephant Shark Genome Project was launched with the aim to ...
One ghost shark was caught on camera swimming off the coast of California in 2017. The specimens studied by NIWA to make this identification were found during other research studies for Fisheries ...
Chimaeras, also known as rat fish, or ghost sharks, include three living families and a little over 50 species of surviving holocephalans. These fishes move by using sweeping movements of their large pectoral fins. They are deep sea fish with slender tails, living close to the seabed to feed on benthic invertebrates. They lack a stomach, their ...
Scientists from the Shark Specialist Group, a division of the International Union for the Conservation of Nature, said that 16 per cent of ghost shark species are “threatened” or “near ...
DNA analysis found the new species had at least 7.9% genetic divergence from other ghost shark species. The research team included David Ebert, Tassapon Krajangdara, Fahmi and Jenny Kemper.
A beached specimen of Hydrolagus novaezealandiae found in Marlborough. 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]
