Question: If frogs call to attract a mate they must be able to hear. How do they do it? Do they have ears?
Answer: Frogs do attract mates by calling. They do hear, but do not have external fleshy protrusions like what we call "ears." The frogs have an exposed eardrum call a tympanum on each side of their heads. The tympanum is bigger and more obvious on species in the Rana family. The tympanum is a round circle usually right behind the eye. A great species for you to see the tympanum on is a bullfrog. You can even sex a bullfrog by the size of the tympanum. The male has a much larger one than the female. I hope this answers your question about how frogs hear
