Generally speaking, the sex of small young turtles (generally weighing less than 250 grams) is difficult to determine because of their immature sex. When some JS sells young Brazilian tortoises, they say that the gender can be determined based on the pattern on the plastron, which has no scientific basis at all. Among turtles of the same age, females are often larger than males. The rare Brazilian tortoise male turtles generally weigh up to 300 grams, and the female turtles generally weigh 500 grams. Other turtles have different sizes due to different species.
Brazilian turtle
Generally speaking, for rare turtles, whether water turtles or tortoises, the gender can often be determined through the following gender characteristics:
1. Female Turtle
The carapace is short and wide, the plastron is flat with no depression in the center, the tail is thin and short, the tail base is thin, the cloaca is close to the rear edge of the plastron, and the two anal shields of the plastron are The notch produced is shallow and the notch angle is large.
2. Male turtles
The carapace is long and narrow, the center of the plastron is slightly inward, the tail is thick and long, the base of the tail is thick, and the cloaca is far from the rear edge of the plastron. Farther away, the two anal shields of the plastron have deeper notches and a smaller notch angle. For most common species of adult turtles, the male turtles are thinner and smaller; the female turtles are rounder, thicker and larger. < p > , separate the index and middle fingers to force the turtle's forelimbs and head into the shell, and shake the turtle's tail straight with your right hand. If there is a black penis sticking out of the turtle's cloaca hole, it is a male; if there are no bubbles in the turtle's cloaca hole, or thin mucus, it is female.
