About the American Toad
The American toad (Anaxyrus americanus) is a common species of toad found throughout the eastern half of Canada and the United States. It is divided into three subspecies: the eastern American toad (A. a. americanus), the dwarf American toad (A. a. charlesmithi) and the rare Hudson Bay toad (A. a. copei). Taxonomic treatments in 2006 placed this species in the genus Anaxyrus instead of Bufo.
A. americanus lays eggs in two long ropes of 2,000-20,000 small black eggs (1-2mm in diameter) surrounded by jelly. Egg strings are in shallow water, typically entwined around vegetation or laying on the bottom of the pond.
American Toad eggs hatch into tadpoles in 3-12 days. The hatched tadpoles, while very small, are recognizable by their skinny tails in relation to the size of their round black bodies. They reach adulthood in 50–65 days. When metamorphosis is complete, the "toadlets" may stay in the water for a short period of time before transitioning to be mostly land based. Often times, groups of tadpoles reach the toadlet stage at once and a begin a mass migration to higher ground. Typically, toadlets migrate to shaded areas in the mid-range and upland forests...
