How does frogs moist skin help them survive?
Moist skin helps in respiration. A thin film of water is formed on the surface of the frog, into which the atmospheric oxygen gets dissolved and ultimately diffuses into the blood vessels underlying the skin. This is the reason, the skin of frog is richly vascular. Some amphibian species don't even have lungs but obtain all their oxygen this way. Frogs do have lung, though, but they still need to breathe through their skin as well.

Why is the skin of frog always moist?
Skin is the respiratory organ in frogs. A thin water film is formed on the skin of frog and to retain this thin film of water for long time, mucus is produced by the mucus glands present in the skin. The O2 gets dissolved into this thin film of water from where it gets diffused into the blood capillaries. And this is the reason, why the skin of frog is richly supplied with blood capillaries. If the skin of frog dries up, the frog dies. The frogs also have lungs but 80% of respiration takes place through the skin. So, frogs have two respiratory organs 1) Skin 2) Lungs.
