Australian green tree frog by the preservative and appeared blue. The color of the frog is caused by blue and green pigments covered in a yellow layer; the preservative destroyed the yellow layer and left the frog with a blue appearance. The specific epithet, "caerulea", which is Latin for blue, has remained. This frog is sometimes referred to as "Pelodryas caerulea" in the scientific literature. In Australia, the frog is also known more simply as the "green tree frog", but that name is often given to the most common green arboreal species in a region, such as the American green tree frog ("Hyla cinerea").
