Coelacanths are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. As sarcopterygians, they are more closely related to lungfish and tetrapods than to ray-finned fish.
The Victoria and Albert Museum in London is the world's largest museum of applied arts, decorative arts and design, housing a permanent collection of over 2.8 million objects. It was founded in 1852 and named after Queen Victoria and Prince Albert.
Sarcopterygii — sometimes considered synonymous with Crossopterygii — is a clade of vertebrate animals which includes a group of bony fish commonly referred to as lobe-finned fish. These vertebrates are characterised by prominent muscular limb buds (lobes) within their fins, which are supported by articulated appendicular skeletons. This is in contrast to the other clade of bony fish, the Actinopterygii, which have only skin-covered bony spines supporting the fins.
Latimeria is a rare genus of fish which contains the two only living species of coelacanth. It includes two extant species: the West Indian Ocean coelacanth and the Indonesian coelacanth. They follow the oldest known living lineage of Sarcopterygii, which means they are more closely related to lungfish and tetrapods than to the common ray-finned fishes and cartilaginous fishes.
Marjorie Eileen Doris Courtenay-Latimer was a South African museum official, who in 1938, brought the existence of the coelacanth, a fish thought to have been extinct for 65 million years, to the attention of the world.
Kelvingrove Art Gallery and Museum is a museum and art gallery in Glasgow, Scotland, managed by Glasgow Museums. The building is located in Kelvingrove Park in the West End of the city, adjacent to Argyle Street. Kelvingrove Art Gallery and Museum is one of Scotland's most popular museums and free visitor attractions.
James Leonard Brierley Smith was a South African ichthyologist, organic chemist, and university professor. He was the first to identify a taxidermied fish as a coelacanth, at the time thought to be long extinct.
The West Indian Ocean coelacanth is a crossopterygian, one of two extant species of coelacanth, a rare order of vertebrates more closely related to lungfish and tetrapods than to the common ray-finned fishes. The other extant species is the Indonesian coelacanth.
Chinlea is an extinct genus of late Triassic Mawsoniid coelacanth fish found in and named after the Chinle Formation that crops out in the southwestern states of Arizona and New Mexico. The word “Chinle” comes from the Navajo word meaning "flowing out", referencing the location where water flows out of the Canyon de Chelly. They were also possibly found in the Dockum Group.
The Iziko South African Museum, formerly the South African Museum, is a South African national museum located in Cape Town. The museum was founded in 1825, the first in the country. It has been on its present site in the Company's Garden since 1897. The museum houses important African zoology, palaeontology, and archaeology collections.
Coelacanthus is a genus of extinct marine coelacanths known from the late Permian period. It was the first genus of coelacanths described, about a century before the discovery of the extant coelacanth Latimeria. The order Coelacanthiformes is named after it.
The Indonesian coelacanth, also called Sulawesi coelacanth, is one of two living species of coelacanth, identifiable by its brown color. The Indonesian coelacanth is a eukaryotic animal within the phylum Chordata, belonging to the class Sarcopterygii and order Coelacanthiformes, classified under the family Latimeriidae and genus Latimeria. As a deep-sea predator, this species plays a crucial role in maintaining the balance of marine ecosystems.
Axelrodichthys is an extinct genus of mawsoniid coelacanth from the Cretaceous of Africa, North and South America, and Europe. Several species are known, the remains of which were discovered in the Lower Cretaceous (Aptian-Albian) of Brazil, North Africa, and possibly Mexico, as well as in the Upper Cretaceous of Morocco (Cenomanian), Madagascar and France. The Axelrodichthys of the Lower Cretaceous frequented both brackish and coastal marine waters while the most recent species lived exclusively in fresh waters. The French specimens are the last known fresh water coelacanths. Most of the species of this genus reached 1 metre to 2 metres in length. Axelrodichthys was named in 1986 by John G. Maisey in honor of the American ichthyologist Herbert R. Axelrod.
The Paleozoological Museum of China is a museum in Beijing, China. The same building also houses the Institute of Vertebrate Paleontology and Paleoanthropology of the Chinese Academy of Sciences. The museum contains exhibition halls with specimens aimed at the public, while the rest of the building is used for research purposes.
Mawsonia is an extinct genus of prehistoric coelacanth fish. It is amongst the largest of all coelacanths, with one quadrate specimen possibly belonging to an individual measuring 5.3 metres in length. It lived in freshwater and brackish environments from the late Jurassic to the mid-Cretaceous of South America, eastern North America, and Africa. Mawsonia was first described by British paleontologist Arthur Smith Woodward in 1907.
Chagrinia is an extinct genus of prehistoric marine coelacanth which lived during the Late Devonian period.
Whiteia is an extinct genus of prehistoric coelacanth fish which lived during the Triassic period. It is named after Errol White.
Heptanema is an extinct genus of prehistoric coelacanth from the Middle Triassic (Ladinian) of northern Italy and southern Switzerland.
Sassenia is an extinct genus of prehistoric coelacanth lobe-finned fish that lived during the Early Triassic epoch in what is now East Greenland and Svalbard.
Fins are moving appendages protruding from the body of fish that interact with water to generate thrust and help the fish swim. Apart from the tail or caudal fin, fish fins have no direct connection with the back bone and are supported only by muscles.
