The Australian green tree frog (Ranoidea caerulea), also known as simply green tree frog in Australia, White's tree frog, or dumpy tree frog, is a species of tree frog native to Australia and New Guinea, Green Tree Frogs are sometimes called the “The smiling croaker.” Their life spans are longer than most of their frog cousins and can reach between 16 to 20 years in captivity. In the wild, their lives are shorter due to predators. An amazing, less known fact about this frog is that its soft, green skin secretes compounds with antiviral and antibacterial properties. Did you know that a group of frogs is called an ‘army’? (A group of toads is called a ‘knot’.) Frogs don’t drink water they absorb it through their skin.
