 The cane toad has poison glands , and the tadpoles are highly toxic to most animals if ingested . Because of its voracious appetite , the cane toad has been introduced to many regions of the Pacific and the Caribbean islands as a method of agricultural pest control . The species derives its common name from its use against the cane beetle ( <unk> <unk> ) . The cane toad is now considered a pest and an invasive species in many of its introduced regions ; of particular concern is its toxic skin , which kills many animals , both wild and domesticated . Cane toads are particularly dangerous to dogs .
