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 ...
Coelacanths (/ ˈ s iː l ə k æ n θ / ⓘ 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 .
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 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 ...
The fish is legally protected through the Minister of Forestry Regulation No. 7/1999. [14] However, it continued to be caught by local fishermen; on November 5, 2014, a fisherman found a specimen in his net, the seventh Indonesian coelacanth found in Indonesian waters since 1998. [15] Eight have been caught as of 2018. [16]
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 ...
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.
Dunkleosteus. Dunkleosteus is an extinct genus of large arthrodire ("jointed-neck") fish that existed during the Late Devonian period, about 382–358 million years ago. It was a pelagic fish inhabiting open waters, and one of the first apex predators of any ecosystem. [1]
