The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad which is native to South and mainland Middle America, but has been introduced to various islands throughout Oceania and the Caribbean, as well as northern Australia. It is a member of the genus Rhinella, but was formerly in the genus Bufo, which includes many different true toad species found throughout Central and South America. The cane toad is a prolific breeder; females lay single-clump spawns with thousands of eggs. Its reproductive success is partly because of opportunistic feeding: it has a diet, unusual among anurans, of both dead and living matter. Adults average in length; the largest recorded specimen weighed 2.65 kg (5.8 lb) with a length of from snout to vent.
