Since frogs spend most of their lives in water there is a huge advantage to having a redundant system of getting oxygen. The need for a frog to be able to breathe without surfacing during the winter months makes "skin breathing" very advantageous. The use of lungs is effective when the frog is on the surface (especially when completely out of the water).
