Water proof?

Question

Are frogs water proof?
A few years ago I had a teacher who would say "are frogs water proof" if you asked a yes or no question. Most of the time I didn't know the answer to the question because it was way out of my league, and he never told us the answer to are frogs water proof. So, are they?

Answer 1

A frog's skin is not waterproof, frogs can absorb both oxygen and water through their skin.

Hylid frogs of Australia can wrap themselves in a transparent waterproof cocoon to keep themselves moist during the summer when they burrow underground to escape the suns heat - The cocoon is made out of dead skin cells.

Answer 2

Frogs, or Rana as the species is known in Latin, are amphibious. This means that they can breath air AND water. They CAN also absorb air through their skin whilst they are under the water. Plus, their skin CAN protect them from mud and certain elements that are in the water too. So yes and no, a frogs skin is both water-proof and porous(allowing water and air through it if needed.).
