A bullfrog is a large amphibian species native to North America. It is characterized by its robust build, smooth skin, and distinctive deep call that sounds like a deep "jug-o-rum." Bullfrogs are known for their voracious appetites and are opportunistic predators, feeding on a wide range of prey including insects, small mammals, birds, and even other amphibians. They are excellent swimmers and have powerful hind legs that allow them to leap long distances. Bullfrogs are commonly found in freshwater habitats such as ponds, lakes, and marshes, and are known for their ability to thrive in a variety of environments. They are a popular subject of study in biology and ecology due to their ecological importance and unique life history traits.
