A tetrapod is a vertebrate animal with four limbs. "Tetra" means "four" and "pod" means "foot". Amphibians, reptiles, birds and mammals are all tetrapods; even snakes and other limbless reptiles and amphibians are tetrapods because they descended from animals which had four limbs. Whales and other cetaceans are also tetrapods because they are mammals have two front limbs and the two hind limbs are vestiges.
Whales are aquatic mammals, not amphibians.

All mammals have four legs, or at least four limbs if they're bipedal such as us, or in the case of bats. Whales have vestigial hind legs, in the form of a pelvis hidden halfway down their tail, and the flippers are their front legs.
