Bullfrogs are brown to green in color, often with dark brown spots. Their bellies range from white to yellow and are sometimes marked with black spots or patterns. Their hind feet are fully webbed.

Male bullfrogs emit a deep bellow that sounds like “jug-a-rum.” Extremely territorial, they will aggressively defend their land, even wrestling with rivals.

Females lay thousands of eggs (as many as 20,000) during the summer breeding season. In the southern part of a bullfrog’s range, metamorphosis can take as few as 79 day; in the colder, northern part of their range, it can take two to three years.
