Chimaeridae
The Chimaeridae, or short-nosed chimaeras, are a family of cartilaginous fish. They resemble other chimaeras in general form and habits, but have short, rounded snouts, without the modifications found in related families. Many species have long, tapering tails, giving them an alternative name of ratfish. Shortnose chimaeras have a venomous spine on their backs, which is sufficiently dangerous to injure humans. They are found in temperate and tropical marine waters worldwide. Most species are restricted to depths below , but a few, notably the spotted ratfish and rabbit fish, can locally be found at relatively shallow depths. They range from in maximum total length, depending on species. Species The species are grouped into two genera and include: Family Chimaeridae * Genus ''Chimaera'' Linnaeus, 1758 ** '' Chimaera argiloba'' Last, W. T.

Hydrolagus Colliei
The spotted ratfish (''Hydrolagus colliei'') is a chimaera found in the north-eastern Pacific Ocean. Often seen by divers at night in the Pacific Northwest, this cartilaginous fish gets its characteristic name from a pointed rat-like tail. The ratfish lays leathery egg cases on the bottom of muddy or sandy areas, which are often mistaken by divers as something inanimate. While mainly a deep-water species, it occurs at shallower depths in the northern part of its range. The generic name, ''Hydrolagus'', comes from the Greek words ὕδωρ, meaning water,Liddell, H.G. & Scott, R. (1940).

Oxford: Clarendon Press. and λαγώς/λαγῶς, meaning hare, and the specific name honors Alexander Collie, who was a ship surgeon and early naturalist.

Discovery The whitespot ghost shark was first described in 2006 by Kimberly Quaranta, Dominique Didier, Douglas Long, and David Ebert in ''Zootaxa''. The specific name, ''alphus'', is Latin and refers to the white spot on its skin. Because the species' habitat is too rough for trawls to operate in, the species has only been discovered using submersibles.

Hydrolagus Bemisi
The pale ghost shark (''Hydrolagus bemisi'') is a shortnose chimaera of the family Chimaeridae. It is endemic to New Zealand waters. Taxonomy This species was first described by Dominique A. Didier in 2002. 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. Description Estimations of growth and age have only been attempted for a quarter of the species known.Finucci, B, Cheok, J, Ebert, DA, Herman, K, Kyne, PM, Dulvy, NK. Ghosts of the deep- Biodiversity, fisheries, and extinction risk of ghost sharks, Fish Fish. 2021; 22: 391-412. https://doi.org/10.1111/faf.12526 This species has a medium-sized body with a tapered whip-like tail. Its length is up to 1.12 m. It can be distinguished from '' H. novaezealandiae'' and '' H. homonycteris'' as it has a pale silvery colour with no patternation or spots.

Fish
Fish are aquatic, craniate, gill-bearing animals that lack limbs with digits. Included in this definition are the living hagfish, lampreys, and cartilaginous and bony fish as well as various extinct related groups. Approximately 95% of living fish species are ray-finned fish, belonging to the class Actinopterygii, with around 99% of those being teleosts. The earliest organisms that can be classified as fish were soft-bodied chordates that first appeared during the Cambrian period. Although they lacked a true spine, they possessed notochords which allowed them to be more agile than their invertebrate counterparts. Fish would continue to evolve through the Paleozoic era, diversifying into a wide variety of forms. Many fish of the Paleozoic developed external armor that protected them from predators. The first fish with jaws appeared in the Silurian period, after which many (such as sharks) became formidable marine predators rather than just the prey of arthropods. Mos ...
