The octagonal turtle is a type of tortoise. Male and female are mainly identified by observing their external characteristics. Generally speaking, the appearance of female star turtles is rounder than that of males, with a flatter back shell, a lighter color on the back, and a shorter and wider tail.
The appearance of male octagonal turtles is more prominent, with a higher back shell, a darker color on the back, and a longer and thin tail. In addition, the claws of male Octopus turtles are longer and thicker than those of females. However, it should be noted that these characteristics are not absolute, and the appearance of some octagonal turtles will be different, so it is best to identify them through professional breeders or veterinarians.
