Detailed explanation-1: -Amphibians are vertebrates (animals with backbones) which are able, when adult, to live both in water and on land. Unlike fish, they can breathe atmospheric oxygen through lungs, and they differ from reptiles in that they have soft, moist, usually scale-less skin, and have to breed in water.
Detailed explanation-2: -Frogs, when present in water, breathe through their moist skin. This kind of exchange of gases is called as cutaneous respiration.
Detailed explanation-3: -All amphibians spend part of their lives in water and part on land, which is how they earned their name-“amphibian” comes from a Greek word meaning “double life.” These animals are born with gills, and while some outgrow them as they transform into adults, others retain them for their entire lives.
Detailed explanation-4: -Amphibians are animals that have special adaptations and can live on both land and in water. Examples include the frog and salamander.
Detailed explanation-5: -Tadpoles and some aquatic amphibians have gills like fish that they use to breathe. There are a few amphibians that do not have lungs and only breathe through their skin.
