Hi

Anyone out there can tell me how to tell the sex of a juvenile and adult bullfrog.

Any advice will be helpful.

Thanks

Males have a Tympanic membrane (ear drum)is larger than its eye, an in female bulls it is approx. the same size!
Hope that helps

You mean that males have tympanic membranes larger than their eye and females have tympanic membranes smaller than their eye. That is how I understood you.

Thanks.
