The bowfin (Amia calva) is a ray-finned fish native to North America. Common names include mudfish, mud pike, dogfish, grindle, grinnel, swamp trout, and choupique.It is regarded as a relict, being one of only two surviving species of the Halecomorphi, a group of fish that first appeared during the Early Triassic, around 250 million years ago.
Amia, commonly called bowfin, is a genus of ray-finned fish related to gars in the infraclass Holostei. They are regarded as taxonomic relicts , being the sole surviving species of the order Amiiformes and clade Halecomorphi , which dates from the Triassic to the Eocene , persisting to the present.
The bowfin and the eyespot bowfin (Amia ocellicauda) are the only two species to survive today, although additional species in all four subfamilies of Amiidae are known from Jurassic, Cretaceous, and Eocene fossils. [1] Bowfins are now found throughout eastern North America, typically in slow-moving backwaters, canals, and ox-bow lakes.
Fish portal; Holostei is a group of ray-finned bony fish.It is divided into two major clades, the Halecomorphi, represented by the single living genus, Amia with two species, the bowfins (Amia calva and Amia ocellicauda), as well as the Ginglymodi, the sole living representatives being the gars (Lepisosteidae), represented by seven living species in two genera (Atractosteus, Lepisosteus).

Possible specimens of caturoids are known from the Late Triassic, with the earliest unambiguous members being known from the Early Jurassic. [4] Amiiformes had spread to North America and Africa by the end of the Middle Jurassic, reaching an apex of diversity during the Early Cretaceous, during the Late Cretaceous and Cenozoic, the group declined until only a single genus, Amia, containing the ...
Amia ocellicauda, the eyespot bowfin, is a species of bowfin native to North America. Originally described by John Richardson from Lake Huron in 1836, it was synonymized with Amia calva until genetic work in 2022 revealed them to be separate species. [ 1 ]

Halecomorphi is a taxon of ray-finned bony fish in the clade Neopterygii.The only extant Halecomorph species are the bowfin (Amia calva) and eyespot bowfin (Amia ocellicauda), but the group contains many extinct species in several families (including Amiidae, Caturidae, Liodesmidae, Sinamiidae) in the order Amiiformes, as well as the extinct orders Ionoscopiformes, Panxianichthyiformes, and ...
