ANATOMY

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. Frogs begin their lives as tadpoles.

Detailed explanation-3: -Famously, the lungless salamanders have neither lungs nor gills – they just breathe through their skin!

Detailed explanation-4: -Amphibians are different from reptiles because they do not have any scales. Instead, they have smooth, slimy skin. An amphibian’s skin is incredibly moist. This allows it to breathe through its skin.

Detailed explanation-5: -Frogs breathe through their when they are underwater, and through when they are on land. Q. Assertion (A)-Amphibians such as frogs can breathe underwater as well as on land. Reason (R)-Frogs breathe through lungs on land and through their moist and slimy skin underwater.
