Bullfrog

Rana catesbeiana

Description:

American bullfrogs live longer in warm weather. Females have eardrums (tympana) the same size as their eyes. The males' eardrums are larger. We had a temperature of 103° F today, so the frogs in my pond were happy, I think. They were not croaking but the smaller one (a female, I believe) was constantly opening and closing her mouth, which serves to ventilate the buccal cavity and exchange gases through the richly vascularized lining of the mouth. The larger male just observed with his mouth closed.

Habitat:

Seen in my yard.

Thanks, Lisa, Jeannette and Karen! She does look happy rather than being in the throes of heavy breathing. :>)

Nice spot. Looks like this one is doing a little skin sloughing. :-)
