Does a frog breathe through its nose?

spacer Croaks and Oxygen

A frog gets a little air into its nose, but not much. Most of it goes through its skin where many blood vessels absorb the oxygen into the blood stream. Some animals have skin that is so thin, that gases like oxygen can pass through it--this process is called cutaneous gas exchange. This is why the frog can breathe through its skin as well as its lungs. It gets 80% of its oxygen this way, but it only works if the frog's skin is moist.

When a frog hibernates, it needs so little oxygen that it just breathes through its skin.
