Bullfrogs and Green frogs are very similar, the way you can tell the difference is by the dorsolateral fold. You can see the fold that wraps around the tympanum (ear), then ends. That means this is a Bullfrog. But Green frogs have the fold that wraps around the tympanum then also has a fold that extends back from the ear and down the back to the thigh. Just for future reference :)
