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 ...
Restoration of C. granulatus. Coelacanthus bears a superficial similarity to the living coelacanth Latimeria, though it was smaller, and had a more elongated head.Individuals grew up to 0.7 metres (2.3 ft) in length, had an elongate codavypter or supplementary tail lobe, and had small lobed fins, suggesting that Coelacanthus were open-water predators.
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 ...
Latimeriidae is the only extant family of coelacanths, an ancient lineage of lobe-finned fish. It contains two extant species in the genus Latimeria, found in deep waters off the coasts of southern Africa and east-central Indonesia. In addition, several fossil genera are known from the Mesozoic of Europe, the Middle East, and the southeastern ...
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 critically endangered. [4]
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, [1] North Africa, [2] and possibly Mexico, [3] [4] as well as in the Upper Cretaceous of Morocco (), [5] Madagascar (Coniacian –Santonian) [2] and France ...
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 ...
