Cane Toads can grow to be quite portly fellows. They're native to South & Central America, but are currently overrunning Australia in creepy numbers. Silly Australians introduced the Cane toads to Queensland in the 1930s in a well-intentioned effort to cut down on their beetle population. The toads have since spread out all across the country, and now there are an estimated 200 million toads!
Australian scientists have discovered that these freaky critters often travel about a mile's distance overnight, as if on some sort of quest. However, because toads aren’t traditionally built for long distance movement, many of them have begun to get arthritis of the spine!
Oh! The toad drama!
