Bufo is a large genus of about 150 species of true toads in the amphibian family BufonidaeTrue toads have in common stocky figures and short legs, which make them relatively poor jumpers. Behind their eyes, Bufo species have wart-like structures, the parotoid glands. These glands distinguish the true toads from all other tailless amphibians. They secrete a fatty, white poisonous substance which acts as a deterrent to predators.
This is a truly cosmopolitan genus, able to live under adverse conditions, and occurring around the world except in the Arctic and Antarctic, Madagascar, Australia (with the exception of the introduced cane toad), and New Guinea and Oceania.
