Cane toads are native to parts of Central and South America. They were introduced to Australia in the 1930s to help control cane beetles. Cane toads have lethal toxins in their skin and release them from glands when attacked by predators. Cane toads disrupt food webs in Australia because they
reduce populations of local species
increase the stability of ecosystems
preserve beetles that feed on crops
provide a potential source of medicine
