  • Bowfins are an order (Amiiformes) of primitive ray-finned fish. Only one species, the bowfin Amia calva, family Amiidae, exists today, although additional species in six families are known from Jurassic, Cretaceous, and Eocene fossils. These included the huge Leedsichthys, the biggest fish that ever existed. The bowfin and the gar are two of the freshwater fishes still extant that existed, almost unchanged from their current form, while the great dinosaurs roamed the earth.
