Australian Common Green Treefrog (Litoria caerulea)
This large treefrog has thick, fleshy skin between the eyes and shoulders. Although usually green, it can be brown, blue or almost black. It has a short and rounded snout, often with an irregular white stripe or series of spots from the corner of its mouth to its forearm. This treefrog has a white belly; its fingers and toes are one-third and three-quarters webbed respectively. Adult Common Green Treefrogs are about 100 mm in length, although they can grow larger than this.
Common Green Treefrogs occupy a wide range of habitat types, including forests, arid areas and mangrove edges. Although becoming scarce in many urban areas, Common Green Treefrogs are still abundant in parts of rural Queensland, where they inhabit toilet cisterns, shower blocks, water tanks and downpipes.
Outside Queensland, Common Green Treefrogs are found across central NSW, north-east SA, much of the NT to the Kimberleys in WA. Common Green Treefrogs are also found in southern New Guinea.
