Birds, reptiles and most amphibians breathe through lungs.
Reptiles (snakes, lizards, crocodiles etc) breathe using lungs. If they are underwater they have to come to the surface to breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin. They can also gulp air into their primitive lungs using their mouth or throat.
