- 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.
