Instructions
Look at the size of the turtle and compare it to other turtles of the same species, if possible. Generally, female turtles are larger than male turtles.
Compare tails of the turtles. Male turtles usually have thicker, longer and larger tails than female turtles.
Examine the claws of the turtles. Male turtles have longer front claws than female turtles.
Check the underside of the turtles. Male turtles often have a concave area on the underside of the shell and female turtles have a rounded area on the underside of the shell. The shape of the male's shell underside helps him stay balanced on the female during breeding.
Look at the turtle's eyes. According to the PetPlace website, male box turtles have red eyes and male Asian leaf turtles have silver eyes. The females of these turtle species have eyes with duller colors.

Tell the difference between a female or male turtle by careful examination of the turtle's body. When you know what you are looking for, you can determine gender and know if you're holding a male or a female.
