Predators in Australia are not adapted to the cane toad's toxin, which is its main defense mechanism. Because of this, toads do not tend to hide and are usually targeted by predators, which then expose themselves to the toxic effects. One study suggests Australian reptiles are greatly threatened by invasion of the cane toad, more so than any other group. Two species of crocodiles and around 70 species of freshwater turtles were found to be at risk of invasion, and all species studied were found capable of eating a toad large enough to kill them. All freshwater turtles and crocodiles are predicted to share part of their future distribution with the invasive species by 2030. Australia's varanids and agamids are also at a great risk.
