''Bufo'' is a
genus of
true toads in the
amphibian family
Bufonidae. As traditionally defined, it was a
wastebasket genus containing a large number of toads from much of the world, but following

Description
True toads have in common stocky figures and short legs, which make them relatively poor jumpers. Their dry skin is thick and "warty".
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. Contrary to folk belief, handling toads does not cause warts, however due to the poison they secrete, and bacteria on their skins, a person should wash their hands thoroughly after handling one.Penn State University - How safe is it to hold frogs and toads?

Species
Formerly, the genus ''Bufo'' encompassed many species and was divided into several subgenera. Frost et al. (2006) removed most of the species of former ''Bufo'' to other genera and restricted the name ''Bufo'' to members of the ''Bufo bufo'' group of earlier authors.[Pauly et al., (2009). ''Herpetologica'' 65:115-128.] Now, this genus has been reduced to seventeen extant species:
