Being predatory lizards, goannas are often quite large, with sharp teeth and claws. It is considered to be the largest lizard in Australia and the largest, the perentie

V. giganteus (shown here), can grow over 2.5 m in length. Reaching speeds of up to 40 kilometres per hour, the perentie runs at about the same speed as an Olympic sprinter and

is also able to run on just its two hind legs.
