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 ...
Fishermen sometimes snag a coelacanth instead of an oilfish because they traditionally fish at night, when oilfish (and coelacanths) feed. Before scientists became interested in coelacanths, they were thrown back into the water if caught. Now that they are recognized as important, fishermen trade them to scientists or other officials.
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 means they ...
Coelacanths were thought to be extinct until a live one was caught in South Africa in 1938. Others have been seen and photographed since then. They're usually found in deep, dark waters.
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] It lived in freshwater and brackish environments from the late Jurassic to the mid- Cretaceous ( Tithonian to ...
The evolution of fish began about 530 million years ago during the Cambrian explosion. It was during this time that the early chordates developed the skull and the vertebral column, leading to the first craniates and vertebrates. The first fish lineages belong to the Agnatha, or jawless fish. Early examples include Haikouichthys.
The fish had already died at the time of the discovery, and was found near the shores of La Jolla Cove. Because the fish usually reside in the deep ocean, they are only spotted close to the ...
