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.
Bowfins are now found throughout eastern North America, typically in slow-moving backwaters, canals, and ox-bow lakes. When the oxygen level is low (as often happens in still waters), the bowfin can rise to the surface and gulp air into its swim bladder , which is lined with blood vessels and can serve as a primitive lung .
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).

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]
