Water dragon in our garden

Here is one of the large family of water dragons in our village garden.  They will be going into hibernation soon for winter in Australia.  My grandchildren love rolling grapes along the paths for them to chase and eat.  The kids think it is like Jurassic Park! Amazing lizards really - they can stay underwater for up to 1/2 an hour but mostly they like to sunbake to get their temperature up in order to be active.
