Coelacanth. Coelacanths (/ ˈsiːləkænθ / ⓘ SEE-lə-kanth) (order Coelacanthiformes) are an ancient group of lobe-finned fish (Sarcopterygii) in the class Actinistia. [2][3] As sarcopterygians, they are more closely related to lungfish and tetrapods (which includes amphibians, reptiles, birds and mammals) than to ray-finned fish.
West Indian Ocean coelacanth. The West Indian Ocean coelacanth[6] (Latimeria chalumnae) (sometimes known as gombessa, [2][7] African coelacanth, [8] or simply coelacanth[9]) is a crossopterygian, [10] 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 ...
Coelacanth National Park ( French: Parc National Coelacanth) is a national park off the main island of the Comoros. [1] The park is made up a seascape home to coelacanths and a coral reef which attracts whales and dolphins. [2] Its creation was announced in 2016 as part of a government effort to protect 25% of the Comoros by 2021.
Latimeria. Latimeria is a rare genus of fish which contains the only living species of coelacanth. It includes two extant species: the West Indian Ocean coelacanth (Latimeria chalumnae) and the Indonesian coelacanth (Latimeria menadoensis). They follow the oldest known living lineage of Sarcopterygii (lobe-finned fish and tetrapods), which ...
Indonesian coelacanth. The Indonesian coelacanth (Latimeria menadoensis, Indonesian: raja laut), also called Sulawesi coelacanth, [ 1 ][ 3 ] is one of two living species of coelacanth, identifiable by its brown color. It is listed as vulnerable by the IUCN, [ 1 ] while the other species, L. chalumnae (West Indian Ocean coelacanth) is listed as ...
Binomial name. †Coelacanthus granulatus. Agassiz, 1839. Coelacanthus ("hollow spine") 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. [1] The order Coelacanthiformes is named after it.
The coelacanths were thought to have gone extinct 66 million years ago, until a living specimen belonging to the order was discovered in 1938. A living fossil is an extant taxon that phenotypically resembles related species known only from the fossil record. To be considered a living fossil, the fossil species must be old relative to the time ...
Coelacanthidae is an extinct family of coelacanths found in freshwater and marine strata throughout the world, originating during the Permian, and finally dying out during the Jurassic . The modern-day genus Latimeria is often erroneously thought to be in this family, when, in fact, it is the type genus of the more advanced family Latimeriidae ...
