It looks so different to the Green and golden bell frog we get in New Zealand. Over here, they range from almost completely green with specks of gold; to green with large patches of gold. I wonder if this is a result of natural selection. I imagine they have far more predators in Australia.
@Zoofan15 Green and Golden Bell Frogs are a species with a great range of colour variety ranging from green to dark brown and gold. I read somewhere that their colouration can darken during colder weather and periods of inactivity. In saying that, I don't think I have ever seen a green one.
The NSW Threatened Species document says "The colour of the body varies. Usually a vivid pea-green, splotched with an almost metallic brassy brown or gold. The backs of some individuals may be almost entirely green; in others golden-brown markings may dominate."
