The word "tetrapod" literally translates as "four legs." Most tetrapods have four limbs, not counting the tail. There are some exceptions, snakes being the most obvious.

What is considered the most recent common ancestor of living tetrapods?

a sturdy-finned, shallow-water lobe-fin whose appendages had skeletal supports similar to those of terrestrial vertebratesA Class of lobe-finned fishes known as Sarcopterygians is believed to have given rise to the amphibians and thence to all other air-breathing vertebrates. There are three main Subclasses -- the Rhipidistii, the Dipnoi, and the Actinistia or Coelocanths. The Rhipidistians are the ones that are ancestral to tetrapods. The oldest known amphibians have been found in rocks of the late Ordovicean Period.The Dipnoi are today's lung fishes -- the African, Australian, and South American. The African and South American types are similar in many ways and are probably fairly closely related. The Australian is quite different and is the only one of them that is capable of using its gills as well as its lung for gas exchange.The Coelocanths were thought to be extinct until the late 1930's when one was discovered in the ocean off the east coast of south Africa.
