Tetrapods are amphibians, reptiles, mammals and birds, and this group does not include fish. Sharks are fish. Some tetrapods, such as snakes, have no legs. Other tetrapods, such as whales manatees, some salamanders and amphisbaenians, only have 2 legs, but they are still tetrapods because their ancestor had 4 legs. Tetra = four, and pod
= leg.
