Which of the following organisms can breathe through moist skin?

Amphibians, such as frogs and toads, have moist skin that allows oxygen and carbon dioxide to exchange. 

This is especially important for amphibians because they frequently live in environments with limited access to air. 

Amphibians' moist skin serves as a secondary respiratory surface, supplementing gas exchange in the lungs. 

Amphibians can stay active and survive in aquatic or semi-aquatic environments where they may be temporarily submerged and unable to access air because they can breathe through their skin.
