Now i know there are some of these in SA, but they are horrible crosses. There are two types in Oz. The eastern water dragon and the Gippsland Water dragon. This is the Gippsland water dragon. This colour is unigue to them. These animals live in areas where frost occur. They would thrive in areas like johannesburg.
