A male's tail is generally longer than the carapace (top shell) itself, often extending well past the hind legs when the animal is relaxed. Conversely, the female's tail is slender and tapers to a point, appearing almost delicate in comparison.
Observing Tail Length and Vent Position for Accurate Sexing
If you observe two turtles in this "dancing" position, the turtle on top is invariably the male, relying on that robust tail structure to maintain the embrace. Furthermore, the position of the tail vent—the opening through which waste and reproductive materials exit—is a telltale sign.
In this position, the male's thick tail curls upward to align with the female's tail, allowing for successful reproduction. In males, this vent is located closer to the tip of the tail, while in females, it is positioned much closer to the body, near the plastron.

The female remains passive, her thinner tail curving downward out of the way. This thickness is necessary to house the hemipenes, the male reproductive organs.
