Are there really hallucinogenic frogs?
Australia is desperately trying to show cane toads the exit door. The 4-pound (1.8-kilogram) toads have thrived a bit too well on the island continent ever since their introduction in 1935. People brought the toads — native to the warmer climates in the United States and tropical regions of South America — from Hawaii to eastern Australia to perform pest control on scarab beetles that were ravaging sugar cane crops [source: Cameron]. It seemed like a good idea at the time since the beetles are a preferred snack of the cane toad.
