Article Edit. Learn why people trust wikiHow. There are 6 references cited in this article, which can be found at the bottom of the page. Method 1. Pick up the tortoise. Hold the tortoise in both hands, being careful not to drop it. Hold the tortoise up high enough to be able to see underneath it. Do not flip the tortoise on its back. This is very stressful for the animal.
If the tortoise is too big to lift above your head, try lifting it just slightly off the ground. Then, get down low enough to see underneath it. Look at the lower shell.
The shell underneath the tortoise is called the plastron. Taking a look at this part of the shell is often the easiest way to tell a tortoise's sex. The concave plastron helps the male to more easily mount the female. If the plastron is flat or convex, it is most likely female. A flat or bulging plastron helps the female carry more eggs. Touch the shell to confirm its shape. Determining the shape of the plastron might not be easy with only your eyes.
You can feel the underside of the tortoise to determine if the shape is convex, flat, or concave. Look at the tail end of the plastron. This is called the anal scute. The scute will have an indent that is shaped like a "V" or a "U. A female's anal scute will form a tighter angle, with points close to the marginals.
This offers her more protection. Put the tortoise back down. This can be stressful for them. Return the tortoise to its usual environment as quickly as possible. Look for sex based on coloration if possible. Not all species of tortoise can be sexed based on the color of their shell. However, in general, males will have somewhat brighter coloration than females. This can be especially true when they are mating.
Red-footed tortoises are an exception. In this species, the males are generally the same size as the females. Examine the carapace. The carapace is the upper shell. In a few species, the shape of the carapace can reveal the sex of the tortoise. If you know your tortoise is one of these species, examine the shape of the shell for clues.
