Is crocodile a reptile or an amphibian?


assistant
Crocodiles are reptiles. While they live both on land and in water, that in itself doesn't make them an amphibian. It lacks other amphibian characteristics, like a moist, glandular skin that lacks scales and feathers. 

While a crocodile, like a reptile, has dry, scaly skin that helps prevent water loss and provides them protection. They lay their eggs on ground.
