The cane toad (Rhinella marina) is a large species of toad originally from South America, but now found throughout the Pacific, the Caribbean and tropical areas of north-eastern New South Wales, Queensland and across northern Australia. Cane toads famously have poison glands that exude a powerful toxin known as bufotoxin that can cause death in a wide range of animals, including humans. Cane toads were intentionally introduced to control cane beetles in sugar cane districts, a strategy that failed miserably, and led to its widespread invasion. The animal continues to increase its Australian range to this day.
