How does a koala camouflage?

Red kangaroos are uniquely adapted to their environment, and this includes their natural colouring. Male red kangaroos can be a strong brick-red colour or a pale red, which assists them to blend into their semi-arid habitat. It has been observed that, in the eastern part of the range of the red kangaroo, females are likely to be more grey in colour, which camouflages better with the grey-green vegetation. However, elsewhere within their range both males and females tend to be reddish-brown.
