Stimulus

Adult frogs are vulnerable to dehydration because of their highly permeable skins. Unlike large adult frogs, small adult frogs have such a low ratio of body weight to skin surface area that they cannot survive in arid climates. The animals' moisture requirements constitute the most important factor determining where frogs can live in the north and a wet climate in the south.
