Reptiles breathe air through their nostrils and their mouths into their lungs. They don't have gills and if they swim underwater they have to come to the surface to breathe.
(Amphibians ( frogs, toads, salamanders, newts, and caecilians) are not reptiles. Most amphibians can accept oxygen from water or air through their skin. They can also pump air into their primitive lungs using their mouth or throat to force it down.)
through their nose
Yes they do. Check out http://www.britannica.com/EBchecked/topic/498684/reptile/38473/Respiratory-system
No. All reptiles, both on land and in water, must breath air. Marine reptiles can hold their breath from a considerable time, but must surface to breathe once in a while.
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.
Reptiles have a backbone. They are vertebrates.Reptiles are covered in scales.Reptiles breathe with lungs.Most reptiles lay eggs. Some reptiles, like the boa constrictor, give birth to live young.Almost all reptiles are cold-blooded.
No, when alligators go under water, they are holding their breath.
They do indeed. I should also point out that crocs are reptiles, not amphibians.
Baby reptiles breathe air through their nostrils and their mouths into their lungs, just like adult reptiles.
Reptiles always breathe with lungs. Amphibians may breathe with lungs, gills or through their skin.
No, reptiles usually have thick scaly skin and they can't breathe through their skin. Reptiles breathe using their lungs. If they are underwater they have to come to the surface to breathe. Reptiles have little slits of nostrils and can also mouth-breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin, which is thin and wet.

No, reptiles do not breath through skin.
