The inland taipan, or fierce snake, produces the most toxic venom of any snake world-wide. Although its supposed range is limited to a small area of western Queensland, there have been historical reports of the snake well outside this area, including northern New South Wales and as far as northern South Australia, and the true current range is unknown. Little is known about this snake in the wild. 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.
