· Here is come information about some common and distinct snakes found in Australia
· Bandy Bandy snakes are very distinctive. They are named after the black and white bands around their body and are rarely seen. They grow up to about 54cm
· Green Tree Snake vary in colour from black, brown to blue or a pale green/grey. Their underside is usually a lemon colour
· The Lake Cronin Snake is very rare and only found in the region of Lake Cronin (in Western Australia). They are known to be toxic, although apparently not lethal to people

· The Pygmy Python only grow up to about 61cm - and are Australia's smallest python, and one of the smallest in the world
· The Southern Death Adder is considered to be at risk of extinction. Its bite is potentially fatal to humans although it is not an aggressive snake
