The Fierce snake produces the most toxic venom of any snake in the world. Little is known about this snake in the wild except that it feeds on rats and may live in their burrows. Despite the name, it is not known to be more aggressive than any other snake. The true distribution of the fierce snake is unknown. It was thought to be limited to a small area in western Queensland, but there have been historical reports of it in northern New South Wales and even northern South Australia and Victoria.
