Instructions
Analyze your box turtle's overall coloration. A male turtle will usually be more colorful, especially on the head, neck and legs. If your turtle has the colors red, white, black, green or orange prominently displayed on it, it is likely a boy.
Look at your turtle's eyes. The eyes of a male are generally reddish, whereas a female's are deep brown.
Check out the top of your turtle's head. A male box turtle will have a reddish-toned head and a female will have a brown one.
Look at the plastron, or underside, of your box turtle's shell. A male will sometimes, but not always, have a concave area in the center to allow him to mount a female more easily.
View your turtle's back feet. A female's feet will have longer, straighter toes, whereas a male will have shorter, more curved toes that look like talons.
Look at your turtle's vent area. A male box turtle will have a longer tail, and his vent is placed farther down the tail's length. A female has a shorter tail and her vent is closer to the body so that whe she lays eggs, they do not have to travel as far down the tail's length.
How to Tell the Difference Between a Male & Female Box Turtle
Determining the sex of your box turtle can be helpful if you just got your pet and you want to know what to name it. If you're looking into breeding box turtles, you need to be sure you've got a suitable pair. A box turtle's sex organs are inside its shell, so it can be difficult to determine if yours is male or female. However, sexing your box turtle can be done using other visible characteristics.
