The Four-Legged Vertebrates


The word "Tetrapoda" means "four legs" in Greek. Amphibians, reptiles (including dinosaurs and birds) and mammals are the major groups of the Tetrapoda.


Tetrapods include all land-living vertebrates, such as frogs, turtles, hawks, and lions. The group also includes a number of animals that have returned to life in the water, such as sea turtles, sea snakes, whales and dolphins, seals and sea lions, and extinct groups such as plesiosaurs, ichthyosaurs, and mosasaurs.

Some tetrapods, like whales and snakes, have lost some or all of the four limbs that their ancestors had, but because of their ancestry they are still grouped as tetrapods.
Tetrapods are part of a larger groups called Sarcopterygii, which also includes several groups of lobe-finned fish, such as lungfish and the coelacanth. The Sarcopterygii are just one group of vertebrates, or animals with a backbone.
