How can you tell if a frog is male or female? Look at the ear circles and the color of the throat!
If the ear circle is larger than the eye and the throat is a creamy yellow, the frog is a male. (This frog has a dorsolateral ridge running along its back, which identifies it as a frog, not a bullfrog.)
If the ear circle is the same size or smaller than the eye and the throat is white, the frog is a female. (The lack of a dorsolateral ridge running along the back identifies this frog as a bullfrog.)
