The Cane Toad is the most hated amphibian in the world. The Cane Toad was introduced in a variety of countries to help control pests on sugar cane. With the Cane Toad’s size and appetite, they started to take over these countries and eat anything in their way. To make matters worse, the Cane Toad is highly toxic, causing harm to anything that tries to eat it that has not evolved to withstand the toxins. Countries have tried to remove them but have generally failed, but they haven’t seriously put effort into it.┬áIn their native environment, they are perfectly fine and should be left to be.
