Coelacanths
What are coelacanths? Coelacanths are a curious group of fish, represented by only two extant species: the African coelacanth (Latimeria chalumnae) and the Indonesian coelacanth (Latimeria menadoensis). These large, lobe-finned fish live in and around deep-water caves off the coasts of southeastern Africa and Indonesia. Around two meters in length, the coelacanth looks like no other fish alive....
متن کاملCoelacanths as “almost living fossils”
*Correspondence: Lionel Cavin, Département de Géologie et Paléontologie, Muséum d’Histoire Naturelle, 1 rue Malagnou, CP6434, 1211 Genève 6, Switzerland e-mail: [email protected] Since its usage by Darwin (1859), the concept of “living fossil” has undergone multiple definitions and has been much discussed and criticized. Soon after its discovery in 1938, the coelacanth Latimeria was rega...
متن کاملTwo living species of coelacanths?
During the period of September 1997 through July 1998, two coelacanth fishes were captured off Manado Tua Island, Sulawesi, Indonesia. These specimens were caught almost 10,000 km from the only other known population of living coelacanths, Latimeria chalumnae, near the Comores. The Indonesian fish was described recently as a new species, Latimeria menadoensis, based on morphological differentia...
متن کاملPopulation divergence in East African coelacanths
The coelacanth, Latimeria chalumnae, occurs at the Eastern coast of Africa from South Africa up to Kenya. It is often referred to as a living fossil mainly because of its nearly unchanged morphology since the Middle Devonian. As it is a close relative to the last common ancestor of fish and tetrapods, molecular studies mostly focussed on their phylogenetic relationships. We now present a popula...
متن کاملPredicting Suitable Environments and Potential Occurrences for Coelacanths (latimeria Spp.) Predicting Suitable Environments and Potential Occurrences for Coelacanths (latimeria Spp.)
Extant coelacanths (Latimeria chalumnae) were first discovered in the western Indian Ocean in 1938; in 1998, a second species of coelacanth, Latimeria menadoensis, was discovered off the north coast of Sulawesi, Indonesia, expanding the known distribution of the genus across the Indian Ocean Basin. This study uses ecological niche modeling techniques to estimate dimensions of realized niches of...
