Sexing Your Frogs

Once your fogs are large enough to sex, you should isolate the males from the females so you do not inadvertently sacrifice a female or try to harvest eggs from a male.

As mentioned before, the females are much larger than the males and have the visible cloaca.  The first image shows an adult male and female laevis together, clearly showing the size differences between the sexes.  Next shows a male's nuptial pads, a definitive indicator of sexual maturity.  The remaining pictures show the males (on the right)  and females (on the left) with their individual characteristics that make sexing easy.
