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.
