Australia has long battled with all sorts of harmful, invasive species--and wildlife authorities are concerned that they may soon be facing a new threat from what may be one of meanest-looking of unwelcome guests. The culprit is a particularly troublesome creature called the Snakehead fish, which is able to breath air, allowing it to travel on land to find prey or migrate. Also known by the perhaps more fitting moniker "Fishzilla," the invasive fish has been discovered in parts of Oceania, and it may be only a matter of time until it makes its way to the Australian mainland.According to a report in The Cairns Post, Snakehead fish have already been discovered on the southern coast of the neighboring island to the north, Papua New Guinea. The fish can grow up to three feet in length and are known to eat water birds, snakes and rodents. Snakehead fish are able to venture out of the water in search of prey which it devours whole.
