TetrapodTetrapod

Tetrapods (Greek τετραποδη tetrapodē, equivalent to Latin quadruped, "four-footed") are vertebrate animals having four limbs. Amphibians, reptiles, birds and mammals are all tetrapods; even snakes and other limbless reptiles and amphibians are tetrapods by descent. The earliest tetrapods evolved from the lobe-finned fishes in the Devonian.[1] They are now a dominant part of the terrestrial fauna, representing all known larger land animals. S
