Coelacanths are ancient lobe-finned fish related to lungfish and tetrapods. They were thought to be extinct until 1938, when a living coelacanth was caught off South Africa. Learn about their fossil record, distribution, behavior, and conservation.
Latimeria is a rare genus of fish that includes two living species of coelacanth, a primitive group of lobe-finned fish. The West Indian Ocean coelacanth (L. chalumnae) is a critically endangered species that lives in deep reef and volcanic slope habitats and gives birth to live young.
Mawsonia is an extinct genus of giant coelacanth fish that lived in freshwater and brackish environments from the late Jurassic to the mid-Cretaceous. The type species is Mawsonia gigas, which may have reached 5.3 metres in length, and several other species have been described or disputed.

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 ...
