The answer to the question “How do frogs sleep?” is a rather complex one and requires some background information about frog anatomy.
Frogs have three eyelids: the upper eyelid, the lower eyelid and a third transparent membrane called a nictitating membrane, which is found on top of the eye. The third eyelid is used to clean debris from the eye and to moisten it while they are sleeping.
Frogs have a unique way of breathing while they are asleep. They use their lungs as well as their skin to breathe while they are in a state of torpor, or hibernation. The breath through their skin by using their moist skin as an extension of their lung tissue. This allows them to breathe without waking up during periods of hibernation.
Frogs do not have ears but instead have eardrums located on either side of their heads under their eyes. These eardrums send sound vibrations through bone conduction directly into the inner ear where they are processed into electrical signals that are sent to the brain for interpretation as sound.
