Frogs have two sets of eyelids. The first set works much like human eyelids, for the frog closes them to shut out light and wipe its eyes clean. But when frogs dive, they close the second set of eyelids, which are transparent and enable frogs to see clearly as they swim underwater
Frogs have special eyes to see in and out of the water. They have a protective film that covers their eyes, which helps them to see underwater.
A frog does not need to keep its eyes moist as it is nearly always in the water.
They lick them.
This is because the frog skin secretes a mucus that helps keep it moist
The frogs have mucus glands in their skin that secrete mucus. These mucus glands keep the frog's skin moist so that the diffusion of gases can occur. Oxygen diffuses into the frog's bloodstream and carbon dioxide diffuses out.
They live in cloud forests, wich are very moist.
The integumentary system of a frog has multiple functions. The integumentary system is made up of the skin of a frog, and visually helps to protect the frog - using camouflage. The integumentary system also helps the skin to stay moist when the frog is on land and helps the frog to breathe while underwater.
The nictitating membrane is a translucent membrane at the bottom of the eye that can be pulled up right across the eye. It is not an eyelid because the frog can still see when the membrane is raised. It is used when swimming or when insects are swarming around the frog's eyes, and also for keeping the eyes moist when it is windy.
