Toad \Toad\, n. [OE. tode, tade, AS. t[=a]die, t[=a]dige; of
unknown origin. Cf. Tadpole.] (Zool.)
Any one of numerous species of batrachians belonging to the
genus Bufo and allied genera, especially those of the
family Bufonidae. Toads are generally terrestrial in their
habits except during the breeding season, when they seek the
water. Most of the species burrow beneath the earth in the
daytime and come forth to feed on insects at night. Most
toads have a rough, warty skin in which are glands that
secrete an acrid fluid.

are familiar European species. The common American toad
(Bufo lentiginosus) is similar to the European toad,
but is less warty and is more active, moving chiefly by
