There are many species of Toads in other countries but only the Cane Toad (Rhinella marina) occurs in Australia. This species was introduced to Queensland from Hawaii in an attempt to control cane beetles in the sugar industry and is now a widespread pest. Cane Toads are ground-dwellers and are encountered in a wide range of habitats. However, although often found a long way from water, they must return to water to breed. Cane Toads are large (up to 26 cm body length, but adult specimens of around 10 cm are the norm). They have thick, warty skins, large venom-producing glands behind the ears, fully-webbed toes and a bony ridge on either side of the snout (above the nostril and eye).
