We narrowed it down to either a green frog or a bull frog, but we soon learned that bullfrogs don't have dorso lateral folds and the green frogs do. This frog did not have dorso lateral folds so we know that it is a bullfrog.

Nice drawing and pictures, and great job determining that it was a bullfrog based on the dorsolateral folds!

I found it really helpful to hear why you thought this was a bullfrog not a green frog! Thanks for posting your quality data and great sketch!

Happy observing,
