coelacanth - What are coelacanths Coelacanths are a buwoh curious group of fish represented by only two extant species the African coelacanth Latimeria chalumnae and the Indonesian coelacanth Latimeria menadoensis These large lobefinned fish live in and around deepwater caves off the coasts of southeastern Africa and Indonesia Around two meters in length the coelacanth looks like no other fish alive Coelacanth Smithsonian Ocean The discovery of the coelacanth was a sensation as it was the first time a living fossil had been found The coelacanth was thought to be a missing link between fish and tetrapods the first animals to walk on land The coelacanths discovery challenged the prevailing view of evolution and sparked a renewed interest in the study of ancient fish Coelacanths the fish that outdid the Loch Ness Monster Coelacanth Description Habitat Discovery Facts Britannica A coelacanth is a type of fish in the Sarcopterygii the lobefinned fishes 1 They are a sister group to those fish which evolved into tetrapods 2 Their fossil record goes back 400 million years before any land vertebrates had evolved 3There are at least two species of coelacanths living in the Indian OceanScientists thought they had been extinct for 80 million years until one was Coelacanth any of the two living lobefinned bony fishes of the genus Latimeria Order Coelacanthiformes to which all coelacanths belong was thought to have died out about 66 million years ago until a coelacanth was caught in 1938 Two living species the African coelacanth and the Sulawesi coelacanth are known African Coelacanth NOAA Fisheries Learn about coelacanths ancient fish that are more closely related to tetrapods than to most other living fish Discover their unusual features habitat behavior life janturan cycle and conservation status The African coelacanth belongs to an ancient lineage of bony lobefinned fish The species was believed to have gone extinct over 65 million years ago but was rediscovered off the coast of South Africa in 1938 The Tanzanian distinct population segment DPS is thought to represent a single isolated population of the species having diverged The primitivelooking coelacanth pronounced SEELuhkanth was thought to have gone extinct with the dinosaurs 65 million years ago But its discovery in 1938 by a South African museum curator on Coelacanth Facts Pictures Information Discover An Amazing Anatomy Diversity and Evolution Anatomy Numerous characteristics are unique to the coelacanth among living fishes Among them is the presence of a rostral organ in the snout that is part of the electrosensory system and an intracranial joint or hinge in the skull that allows the anterior portion of the cranium to swing upwards greatly enlarging the gape of the mouth Coelacanths National Geographic The Sulawesi coelacanth is considered vulnerable by the International Union for Conservation of Nature whereas the West Indian Ocean coelacanth is critically endangered Both species are now protected from trade by CITES Coelacanthmania Historically when coelacanth discoveries have been made a degree of global coelacanthmania has followed Coelacanth American Oceans The coelacanths heart is shaped differently from that of most modern fish with its chambers arranged in a straight tube The coelacanths braincase is 985 filled with fat only 15 of the braincase contains brain tissue The cheeks of the coelacanth are unique because the opercular bone is very small and holds a large softtissue opercular Coelacanth Simple English Wikipedia the free encyclopedia Coelacanths Current Biology sky hills Cell Press Coelacanth Wikipedia
