The American bullfrog is a large species of amphibian that lives in the swamps, ponds and lakes of the USA and Canada. Depending on its environment, it may be dark green, pale green or pale brown dorsally with a paler coloured belly. It may have darker spots on its back and a banding pattern on its legs, although some variations of the bullfrog have no pattern. The American bullfrog is sexually dimorphic; females are larger than males, and males have distinctive yellow coloration on their throat and a much larger tympanum (ovular hearing gland) on the sides of their head. The American bullfrog measures between 90-152mm in length and weighs 300-500g.
