These mating bullfrogs were serenely floating in the water while around them was chaos, with males playing leapfrog and wrestling each other into submission and croaking loudly. The male here is the one on top with his characteristic yellow throat and large tympani (the eardrums, the big circles behind the eyes). The water was mostly still but there was a subtle current and they both used their webbed rear feet to control their speed and balance. They don’t have webbing on their front toes, so the female used her front legs to maintain balance while the male has his wrapped around her body.
