The American bullfrog is the largest North American bullfrog. The green color is due to blue pigment in the skin covered by a thin layer of yellow mucus. Many color variations are known including white, bright yellow, bright blue, and black and white.

They breed from about March through July or August. Tadpoles take 6 months to 2 years to mature.
