Detailed explanation-1: -Most amphibians breathe through lungs and their skin. Their skin has to stay wet in order for them to absorb oxygen so they secrete mucous to keep their skin moist (If they get too dry, they cannot breathe and will die).

Detailed explanation-2: -Amphibians can also breathe through their moist, porous skin, and, in fact, several salamander species and one kind of frog have neither gills nor lungs: They get all of their oxygen through their skin.

Detailed explanation-3: -Most amphibians breathe through both skin and lungs. The frog is an amphibian.

Detailed explanation-4: -Amphibians like the Titicaca water frog and hellbender salamander that live in cold, fast-moving streams may be able to breathe through mainly cutaneous respiration. Cutaneous respiration allows the animal to absorb water through their skin directly into their bloodstream.
