This subclass contains the coelacanths Order Coelacanthiformesincluding the two living species of coelacanths, both of the genus Latimeria: Dibujo simplificado de la estructura del sarcoptefygii, por Francisco Collantes. Journal of Vertebrate Paleontology.

Rhipidistians appeared with the Coelacanths, but migrated from marine to freshwater habitats, probably initially near the claes of rivers. They were believed to have gone extinct at the end of the Cretaceous, until the genus Latimeria was discovered off the east coast of South Africa in ; since then, other Latimeria have been discovered in Kenya, Mozambique, Tanzania, Madagascar, and South Africa.

Lobe-finned fish Living fossils Live-bearing fish Ovoviviparous fish Extant Devonian first appearances Vertebrate subclasses. Actinistia Cope Actinistia is a subclass of mostly fossil lobe-finned fishes. Lungfishes used their stubby fins to walk on land and find new water if their waterhole was depleted, with their lungs breathing air, just like modern species do.

The tetrapodomorphs had essentially the same anatomy as lungfishes. Behavior and life history Marine mammals: Orden Temnospondyli Este grupo es uno de los posibles candidatos a ser el antepasado de los anfibios modernos. Johns Hopkins University Press.

The lungfishes evolved the earliest primitive lungs and limbs, peaked in the Triassic, and remain an extant though minor taxon. Ecologia i biologia Amfibis: This page was last edited on 24 Decemberat Cyclostomata Myxini hagfish Hyperoartia lampreys.
