List of toad families

In scientific taxonomy, toads include the true toads (Bufonidae) and various other terrestrial or warty-skinned frogs. Non-bufonid "toads" can be found in the families: * Bombinatoridae ( fire-bellied toads and jungle toads) * Calyptocephalellidae ( helmeted water toad and false toads) * Discoglossidae ( midwife toads) * Myobatrachidae (Australian toadlets) * Pelobatidae ( European spadefoot toad) * Rhinophrynidae ( burrowing toads) * Scaphiopodidae ( American spadefoot toads) *

Biology

Usually the largest of the bumps on a toad's skin are those that cover the parotoid glands. The bumps are commonly called warts, but they have nothing to do with pathologic warts, being fixed in size, present on healthy specimens, and not caused by infection. It is a myth that handling toads causes warts. Toads travel from non-breeding to breeding areas of ponds and lakes. Bogert (1947) suggests that the toads' call is the most important cue in the homing to ponds. Toads, like many amphibians, exhibit breeding site fidelity (

). Individual American toads return to their natal ponds to breed, making it likely they will encounter siblings when seeking potential mates. Although inbred examples within a species are possible, siblings rarely mate. Toads recognize and avoid mating with close kin. Advertisement vocalizations given by males appear to serve as cues by which females recognize kin. Kin recognition thus allows avoidance of inbreeding and consequent
