The Eastern Water Dragon grows to around 80-90cm in length, much of which is tail. The colour is shades of grey or brown with a series of black bands on the back and tail and a black stripe on the side of the head behind the eye. The underside is creamy-white, although males may have a vivid red on some or most of the belly and chest. The diet mainly comprises small reptiles, worms, frogs, insects, vegetation, fruit, small mammals and molluscs.
