[71] [72] Coelacanths usually are caught when local fishermen are fishing for oilfish. 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.
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 ...
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 ...
In 2011, a commercial fisherman accidentally caught the largest alligator gar on record in Mississippi’s Lake Chotard. The gar was 8.5 feet long, weighed 327 pounds and was believed to be 94 ...
Descendants also included pelagic lobe-finned fish such as coelacanth species. In 2000 P. Ahlberg et al. described a transitional form from fish to tetrapod, Livoniana. This creature dates 374–391 million years ago, a successor to Panderichthys. Tiktaalik roseae is the only species classified under the genus.

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.
