Frogs, like most amphibians, need large amounts of water due to their porous, respiring skin. The water-holding frog is no exception, but still manages to survive in the dry, sandy deserts of the Australian outback. How does any amphibian manage such a feat? By carrying its water with it! During dry periods, the frog burrows deep into the ground and produces a mucus-filled cocoon, incorporating shed skin, which encases its entire body. The cocoon lets the frog retain massive quantities of water, allowing it to hibernate for up to two years until the rains come again. Aboriginal Australians have learned to gently squeeze the frog and drink some of its retained water, before releasing the animal unharmed.
