Question

How can you tell the difference between a male and female frog externally?

Answer 1

I hope it would have only small differences ad much as possible. As one can be harder, softer; one may have some dots

Answer 2

Other Physical Differences. A small round disc called the tympanum covers the ears of both male and female frogs. On males of most frog species, the circumference of this small disc is larger than the eye of the frog. On females of most frog species, the disc's circumference is equal to the size of the frog's eye.
