Bufonidae is a family of frogs known as toads and are the only family of frogs exclusively known as toads. True toads comprise a number of genera, with Bufo being the most widespread and known. Only the genus Atelopus are commonly known as frogs.

True toads are widespread and occur natively on every continent except Australia and Antarctica, inhabiting a variety of environments, from arid areas to rainforest.

True toads are generally warty in appearance and have a pair of parotoid glands on the back of their heads. These glands contain a poison which the toads excrete when stressed. The poison in the glands contains a number of toxins causing different effects. Bufotoxin is a general term, different animals contain significantly different substances and proportions of substances.
