Toad of the genus Bufo marinus, family Bufonidae. Also known as the giant or marine toad, the cane toad is the largest in the world. It acquired its name after being introduced to Australia during the 1930s to eradicate the cane beetle, which had become a serious pest there. However, having few natural enemies, the cane toad itself has now become a pest in Australia.
The cane toad's defense system against its few natural enemies consists of highly-developed glands on each side of its neck which can squirt a poisonous fluid to a distance of around 1 m/3.3 ft.
