There are 3 subspecies; the dwarf American toad (A. a. charlesmithi), the eastern American toad (A. a. americanus) and the rare Hudson Bay toad (A. a. copei). They are known to hibernate during the winter.
Female American toad lay eggs in 2 strings and these eggs, when fertilized can hatch in 2 to 14 days. Tadpoles reach adulthood in 50 to 65 days but with help from the Chlorogonium alga, the tadpoles can grow bigger faster. Young tadpoles have toxic chemicals in their skin, which provides a sort of defense mechanism.
