<Li> Rana marina Linnaeus, 1758 </Li> <Li> Bufo marinus Schneider, 1799 </Li> <P> The cane toad (Rhinella marina), also known as the giant neotropical toad or marine toad, is a large, terrestrial true toad native to South and mainland Central America, but which has been introduced to various islands throughout Oceania and the Caribbean, as well as Northern Australia . It is the world's largest toad . 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 10--15 cm (3.9--5.9 in) in length; the largest recorded specimen had a snout - vent length of 24 cm (9.4 in). </P> <P> The cane toad is an old species . A fossil toad (specimen UCMP 41159) from the La Venta fauna of the late Miocene of Colombia is indistinguishable from modern cane toads from northern South America . It was discovered in a floodplain deposit, which suggests the R. marina habitat preferences have long been for open areas . </P>
