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.
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 ...
Mawsonia is an extinct genus of prehistoric coelacanth fish. It is amongst the largest of all coelacanths, with one quadrate specimen (DGM 1.048-P) possibly belonging to an individual measuring 5.3 metres (17.4 feet) in length. [2]
Marjorie Eileen Doris Courtenay-Latimer (24 February 1907 – 17 May 2004) was a South African museum official, who in 1938, brought to the attention of the world the existence of the coelacanth, a fish thought to have been extinct for 65 million years. Marjorie Courtenay-Latimer discovered this coelacanth, formerly only seen in fossils ...
The coelacanth — a giant weird fish still around from dinosaur times — can live for 100 years, a new study found. Females don’t hit sexual maturity until their late 50s, the study said ...
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 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 fishes.
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.
