American Toad (Bufo americanus)
The American Toad is a common species of toad found throughout the eastern United States and Canada.
The eggs of the American Toad are laid in two strings and can hatch in 3-12 days. When hatched they are recognizable by their skinny tails in relation to the size of their bodies. The tadpoles may advance to adulthood in 30-40 days. When completed the toadlets may stay in the water for a short period of time before they become mostly land based.
The Eastern American toad (B. a. americanus) is a medium sized toad usually found in the range from 2 to over 3 1/2 inches. The color and pattern is somewhat variable. They hibernate during the winter. The Eastern American toad has spots that contain only one to two warts. It also has enlarged warts on the tibia or lower leg below the knee. While the belly is usually spotted, it is generally more so on the forward half (in some rare individuals there may be few or no spots). Other species which may be confused with the Eastern American toad are Fowler's toad, which has three or more warts in the largest dark spots, and in the far west of its range Woodhouse's toad. Also, Fowler's toad never has a spotted belly and both cranial crests touch the parotoid glands. In the Eastern American toad these crests almost never touch the parotoid glands, which secrete bufotoxin, a poisonous substance. The poison the toad excretes is mild, but can irritate human skin.
