Bullfrogs

American bullfrog, known mononymously in Canada and America as bullfrogs, are a species of aquatic frog, usually found in swamps, lakes, or ponds. They are noted for their yellow, green, and brown coloring, and the males' distinctive grumbling roar. While these frogs are native to the United States and Canada, they now flourish in Central and South America, Western Europe, and parts of Asia.
