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. White & Pogonoski, 2008 (whitefin chimaera) ** '' Chimaera bahamaensis'' Kemper, Ebert, Didier & Compagno, 2010 (Bahamas ghostshark ...

Chimaera Carophila
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. At one time a "diverse and abundant" group (based on the fossil record), their closest living relatives are sharks and rays, though their last common ancestor with them lived nearly 400 million years ago. Today, they are largely confined to deep water. Description and habits Chimaeras live in temperate ocean floors down to deep, with few occurring at depths shallower than . 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. Consequently, these are also among the few species from the chimaera order kept in public aquaria. They live in all the oceans except for the Arctic and Antarctic oceans. They have elongated, sof ...

David A
David (; , "beloved one") (traditional spelling), , ''Dāwūd''; grc-koi, Δαυΐδ, Dauíd; la, Davidus, David; gez , ዳዊት, ''Dawit''; xcl, Դաւիթ, ''Dawitʿ''; cu, Давíдъ, ''Davidŭ''; possibly meaning "beloved one". was, according to the Hebrew Bible, the third king of the United Kingdom of Israel. In the Books of Samuel, he is described as a young shepherd and harpist who gains fame by slaying Goliath, a champion of the Philistines, in southern Canaan. David becomes a favourite of Saul, the first king of Israel; he also forges a notably close friendship with Jonathan, a son of Saul. However, under the paranoia that David is seeking to usurp the throne, Saul attempts to kill David, forcing the latter to go into hiding and effectively operate as a fugitive for several years. After Saul and Jonathan are both killed in battle against the Philistines, a 30-year-old David is anointed king over all of Israel and Judah. Following his rise to power, David ...

Chimaera Obscura
The shortspine chimaera (''Chimaera obscura''), also commonly known as the short spine chimaera, is a chimaera species in the family Chimaeridae, which lives off of the east coast of Australia. Description The shortspine chimaera is similar to the other species in its genus, but of uniformly dark brown to black colour. It has a robust body, and has a shorter spine than first dorsal fin.

Chimaera Notafricana
The cape chimaera (''Chimaera notafricana'') is a chimaera species in the family Chimaeridae, which lives in South Africa and Namibia. Taxonomy The cape chimaera is one of 16 species in the genus Chimaera. The species was described in 2010 by Kemper, Ebert Compagno and Didier. Prior to 2010, specimens were classified under the species ''Chimaera monstrosa'', commonly known as the rabbit fish, before further studies showed that they had a number of differences in distribution and appearance, enough to classify them as two separate species. Habitat and distribution The cape chimaera is found in the southeast Atlantic Ocean, in the waters off Namibia as well as South Africa, particularly in the Western Cape, Northern Cape Province, and Eastern Cape Province. Its exact population being unknown, but it is thought to be an uncommon species. Although the species is occasionally caught as a bycatch by deepwater fisheries, it is not threatened and is not sought out for commercial pu ...

Chimaera Monstrosa
''Chimaera monstrosa'', also known as the rabbit fish or rat fish, is a northeast Atlantic Ocean, Atlantic and Mediterranean Sea, Mediterranean species of cartilaginous fish in the family Chimaeridae. The rabbit fish is known for its characteristically large head and small, tapering body. With large eyes, nostrils, and tooth plates, the head gives them a rabbit-like appearance, hence the nickname “Rabbit fish”. They can grow to and live for up to 30 years. Description The appearance of ''C. monstrosa'' shares characteristics of its distant relatives, sharks. It characteristically has a large head and a tapering body that ends in its whip-like tail, and has a short snout with an overhanging mouth. The top dorsal fin is positioned high on the spine of the fish, and is triangular and tall in height. Positioned in the mid-section of the fish, the spine runs throughout the length of the fish and continuously joins with the upper part of the caudal fin; this dorsal spine is als ...
