There are a number of ways in which the respiratory system has changed during the development of amphibians. Their respiratory system developed in such a way that they need more oxygen than they used to.

Mammals, birds, reptiles and adult amphibians breathe using lungs. Fish breathe using gills, while juvenile amphibians breathe using gills and spiracles.
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.
