Eastern Water Dragon
The Australian water dragon is an arboreal lizard native to eastern Australia. They have long powerful limbs and claws for climbing and a long muscular laterally-compressed tail for swimming. Males show bolder coloration and have larger heads than females. To give you a reference to the size of this creature the stump on which it is basking is 650mm wide. They have a life span of around 18 to 20 years. They live near creeks, rivers, lakes and other water bodies that have basking sites such as overhanging branches or rocks in open or filtered sun. They are able to remain totally submerged for up to 90 minutes and will use this attribute when escaping from a predator.
They are often sighted around WCC (Websters Creek Community). A few live in my back yard near the dam and frequently bask on an old tree stump nearby.
