Can animals or insects have multiple respiratory organs at the same time? See an example of these animals and insects.

Yes, some species of animals have several respiratory organs at once. This is most common among amphibians. Let’s take a look at the example of frogs. They first have gills at the tadpole stage, when they live only in water. Then they begin to form lungs. When the lungs are formed, the gills are overgrown. Also, in addition to the lungs, frogs can carry out gas exchange using the surface of the skin. Among insects, there are also representatives that can breathe simultaneously through the lungs and the surface of the skin.
