Bullfrog
It belongs to the family Ranidae, or 'true frogs'. Bullfrogs are native to most of North America, Canada and Mexico. The ones that live in northern America hibernate during winter. However, bullfrogs in southern US states are active all the time. Bullfrogs have been seen in South America, Asia, Western Europe and the Caribbean. These bullfrogs were imported on ships. Many people, including pet owners, have placed bullfrogs outside of their native area.
