Can frogs breathe under water?
when frogs are tadpoles they breathe underwater through internal gills, and their skin. And then later develop into land animals and develop lungs for breathing air. Frogs breathe with their mouths closed, the throat sack pulls air through the nose and into their lungs. Frogs nostrils are placed on top of their head so they can be in the water and breathe at the same time just like a crocodile floats and has eyes on top if its head to be on guard.
