Things You'll Need
- Other map turtles
Instructions
Look at the turtle's tail against other maps and notice the thickness and length. If the tail is longer and thicker than the others, the turtle will be male in gender.
Compare the the front claws of the turtle against those of other maps and determine whether they are longer than the other turtles. Many map males have much longer front claws than their female counterparts, such as those that belong to the G. oculifera, G. ouachitensis, G. flavimaculata, G. nigrinoda, and G. pseudogeographica species.
Compare the size of the turtle against other maps. Females are generally the bigger of the two species. The female least biggest in size will be at least as big as the largest male, or bigger.
Observe the turtrle's head and jaws against the other maps. A female map will have a larger head, and broader jaw than the males in many species. This distinguishing characteristic is especially common with the G. pulchra, G. barbouri, and G. geographica species.
