Bufonidae is the true toad family. Their most noticeable and recognizable feature is the pair of parotoid glands on their back of their heads. This gland can produce a toxin when the toads are stressed. The males also have Bidder’s Organ, which allows them to turn into females. The family Bufonidae is found on every continent naturally besides Australia and Antarctica.
The genus Bufo is found throughout Europe and Asia.
The genus Anaxyrus is found in North America and Central America. They are known for their less prominent cranial crests compared to other toads in the area.
