The major differences is the amphibians need for water;
Amphibians must lay their eggs in water (and usually have a fish-like youth stage [tadpoles]) and often need to keep their skin wet in order to "breath" through it

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.
