Instructions
Compare two frogs side by side, if possible.
Check which frog is lighter in color. Female frogs exhibit a duller, lighter coloring than males. Males generally exhibit dark skin.
Confirm the color identification by comparing size. Female frogs grow larger than male frogs, in most cases.
How to Tell a Frog's Gender by Its Color
Many frog species exhibit color differences between the male and female that help pet owners or observers tell them apart. Although many times frogs exhibit gender differences elsewhere on their bodies, such as on the digits on their hands, this method offers the most obvious way to tell the two sexes apart. Learning to tell these variances apart will help you identify male and female frog pets in captivity or in the wild. Note that additional sexing methods, such as checking the digits and assessing overall size, may be necessary to classify a frog as a male or female.
