Bufonidae is a family of true toads. The family has 35 genus groups in it. The Bufonidae toads live almost everywhere, on every continent except Australia and Antarctica. They live in rain forest. They lay their eggs in strings. Mostly, the eggs and become tadpoles. However, in the genus Nectophrynoides, the eggs hatch into small frogs instead.
True toads do not have any teeth. Their skin has bumps called warts. They have a pair of parotoid glands on the backs of their heads. These glands has alkaloid poison. They get this type of poison from stress. They have also other toxins such as Bufotoxin. Male toads has a Bidder's organ. The organ will become an active ovary if conditions are right. They will then become a female.
