Cane Toad

Cane toads are killing off the freshwater crocodiles which make their home in the Victoria River District in Australia. The toads have been credited for the demise of hundreds of these crocs, and don’t show any sign of letting up any time soon.

A group of scientists have been studying the happenings of the Victoria River since 2005, to take a gander at how the toad is effecting the local wildlife.

The leader of the group, Dr. Mike Letnic, has recently returned from a scouting trip to the area.

“I haven’t put all of the figures together yet but when we look at the data from Victoria River Downs, where the cane toads came through in 2006, the crocodile populations are down as much as 80 per cent.

“We did test some crocodiles a few years ago, some of the survivors, but we found no evidence that they had any immunity.

“The other idea we had was that the crocodiles might learn to avoid toads and we found a little bit of evidence in the laboratory, that crocs will learn.

“But in the wild it seems to be a different story, we keep seeing crocodiles chomping on toads.”

Yes, you would think the crocs would learn, however, seems that when a croc goes to chomp a cane toad, none of the other crocs are watching… Seems to me the crocs need to come up with a defensive plan, and soon, before they are all wiped out.
