The gender distinction of Brazilian turtles is mainly based on their physical characteristics, and the following are some of the bases for distinguishing male and female:
Adult Brazilian tortoise:
1.Abdominal carapace morphology: The male turtle's abdominal carapace will be concave inward, while the female turtle's abdominal carapace will remain flat.
2.Tail length: The tail of a male turtle is usually longer than that of a female.
3.Body color changes: As they mature, the male turtle may change its body color to black, while the female turtle retains its original tan color.
4.Cloaca location: Turtles with straight tails, male turtles with cloaca located beyond the edge of the buttocks shield, and female turtles on the contrary.
Juvenile Brazilian tortoise:
1.Body size: Turtles of the same age, females are usually larger than males.
2.Carapace shape: The male turtle has a short and wide dorsal carapace, while the female turtle has a longer and narrow dorsal carapace.
3.Abdominal carapace morphology: The female turtle will have a slight depression in the abdominal carapace**, while the male turtle will not.
4.Tail characteristics: Females have shorter and thinner tails, while males have thicker and longer tails.
5.Cloacal pore location: The cloaca of the female turtle is far from the posterior edge of the ventral carapace, and the gap formed by the shield on the ventral carapace is deep and the angle is smallerIn males, on the other hand, the cloacal foramen is closer to the posterior edge of the ventral carapace, and the notch formed by the shield is shallow and angular at a larger angle.
These characteristics can help us accurately identify the male and female of the Brazilian tortoise, but it is important to note that in practice, these characteristics may vary due to individual differences and environmental factors. Therefore, when discerning, it is necessary to make a judgment based on a combination of multiple characteristics and consult a professional if necessary.
