noun

Definition of cane toad

: a large, brownish, poisonous toad (Rhinella marina synonym Bufo marinus) native to Central and South America, Mexico, and extreme southern Texas and introduced into other tropical and subtropical areas (such as Australia) where it has become an invasive species Cane toads are seen as a major threat to biodiversity, not only because they voraciously out-compete some native species for food and consume others, but also because their skin toxins are thought to kill carnivorous predators which mistake them for local amphibians.— Sheila Lunter
