NEET BIOLOGY

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: -What are the 7 main characteristics of amphibians? Amphibians have a backbone, are cold-blooded, need a moist place to live, can breathe air through their skin, externally fertilize their eggs, eat meat, and grow legs when they mature.

Detailed explanation-4: -Amphibians are frogs, toads, newts and salamanders. Most amphibians have complex life cycles with time on land and in the water. Their skin must stay moist to absorb oxygen and therefore lacks scales.

Detailed explanation-5: -Amphibians have primitive lungs compared to reptiles, birds, or mammals. This means that they deal with slow diffusion of oxygen through their blood. Buccal pumping works by having the amphibian draw in air through its nostrils.
