This frog (Ranoidea caerulea) is also called the White's tree frog or the dumpy tree frog. The former name comes from John White himself, as he first described this species in 1970. Native to Australia and New Guinea, this frog is bigger than the majority of the frogs in Australia (10cm+). Due to their antibacterial and antiviral skin discharge, they have managed to preserve their numbers as other amphibian species experienced declines in population. Over their eyes, they have a fatty area that can be used to identify them. Learn more at https://en.wikipedia.org/wiki/Australian_green_tree_frog
