How do frogs breathe?
|
Tadpoles have feathery gills sticking out of the sides of their necks that allow them to absorb oxygen from the water. Adult frogs need to breathe in air. They have lungs like us and can also absorb some oxygen through the linings of their mouths and through their moist skin. | | A frog |
