White's Tree Frog

The White's tree frog (Litoria caerulea), also known as Dumpy tree frog, is a rather large tree frog with a stout body. Adult females can reach about 4 to 4.5 inches in length, whereas males are more likely to be around 3 inches.

Coloration

Its scientific name, caerulea, means blue color in Latin. However, only a very small minority of White's treefrogs appear as blue. Instead, they are usually seen as dark or bright green. Their skin has a mixture of green and blue pigments with a layer of yellow pigment over the top. When the yellow layer wears off the frog appears in green.

Pictures at below is the uncommon "blue phase", which is a morph of the White's treefrogs originating from Australia. Frogs of the same species from Papua New Guinea, New Zealand and Indonesia tend to have a duller color from yellowish-green to dark brown.
