They are spreading rapidly in the Northern Territory. There is no apparent barrier to prevent them from reaching the Kimberley Region of Western Australia. A prediction, based on the climatic tolerance of the toads, is that they will become established in Darwin early next century and eventually spread over much of the coastal seaboard of Australia. They can not be imported or kept in this state, however special scientific licences have been issued to import them for teaching and research purposes. Identification Giant toads are heavily built, have short legs and no webs between their toes.
Adults have a rough warty skin.
Their colour is tan, dull green or black, with a light underside. They have large glands behind the head which exude a poisonous milky substance when the toads are attacked. The spawn consists of long double chains of black eggs about 1 mm in diameter enclosed in a transparent cover. They develop into tadpoles which form large, slow moving shoals. Food Habits Giant toads are omnivorous.
