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 caims 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.

As if the Snakehead fish weren't enough of a problem, another invasive species is inspiring nightmares for Australian wildlife authorities--the climbing perch. Much like the Snakehead, climbing perch are capable of 'walking' on land, and according to the Post, "may even climb trees." Still, there's no shortage of freaky fish to worry about.

"There are a whole bunch of fish that are now on the southern coast of New Guinea...which are even worse than climbing perch," says Damien Burrows, director of the Australian Centre for Tropical Freshwater Research.

New Guinea is separated from the Australian mainland by the narrow Torres Strait, although Burrows doesn't think that the pests would be able to enter his territory unassisted, but he's still concerned.

What would you do if you saw one of these?

Eat them. The uglier the fish, the tastier the meat.

I agree with SB: in Thailand we make gaeng som with snakehead fish; araoi maaaaak

is it true that snakehead fishes are mutated? i mean that they are two different species of fishes that were mixed together. if so, what fish are they?

Goldfish and a cod ?????
