Amniotic egg

Tortoises
are large semiaquatic reptiles that live throughout the tropics in Africa, Asia, the Americas and Australia.
Crocodiles
The two extant species are the American alligator and the Chinese alligator. Additionally, several extinct species of alligator are known from fossil remains
Alligators
are elongated, limbless, carnivorous reptiles of the suborder Serpentes.
Snakes
are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains.
Lizards
