The correct answer is C. The cane toad is one of the most dangerous and widespread invasive animal species in Australia. In addition to being larger than that of the native species of frogs and competing for resources, the biggest advantage of these species are their poison glands on its back. Native predators in Australia are not aware of its toxicity and hunt and eat them, suffering from poisoning and death after.
