Hawaiian Cane Toads Killing off Australias Crocs

Here in Hawaii we are always worried about invasive species.

Back in 1935, Hawaiian Cane toads were exported to Australia to try and eliminate small beetles.

Instead, they are eliminating the Alligators.  We should think about stories like this when were thinking about using pests to eradicate Strawberry Guava:

Who would have thought a humble toad could end up as the killer of one of the world’s most fearsome creatures, the crocodile? It all started off so innocently, too.

Introduced to Australia in 1935 from Hawaii, the cane toad, which is native to Central and South America, was supposed to kill off the scarab beetles that were decimating Australian sugarcane crops. Unfortunately, the toads failed to go after the beetles and decided to multiply at a very fast rate instead (they can lay between 8,000 and 30,000 eggs in one go) ending up as another pest the Australians were keen to see the back of.

According to the Australian Department of the Environment and Heritage (DEH), the cane toad “expanded through Australia’s northern landscape at 27-50 kilometers a year” and is now heading south at a rate of 1.3 kilometers a year.

Cane toads not only eat pretty much anything that can fit in their mouths, but as of yet, no known predators or diseases have been identified that can take them on. The problem is that they are extremely toxic, with the DEH stating “almost anything that eats the toad dies rapidly from heart failure”. And that includes crocodiles. According to the University of Sydney, crocodile populations that have come across these new pests have been dropping like flies, in some places by as much as 77 percent…
