True Frogs

True frogs of the Ranidae family have the widest distribution of species in the world, occuring on every continent except Antartica. Common characteristics of Rana species include a smooth and moist body, snouts with a sharper edge and strong legs that capatult them over good distances. They tend to live near bodies of water, including streams, rivers, drains and pools in both rainforest and urban habitats. Their calls vary from species to species, often producing interesting sounds such as dog barks and whistles. Some species secrete a toxin from their skin, making them poisonous in nature, such as Rana hosii, the poison rock frog.
