How do grass turtles divide male and female, and how old are grass turtles

Generally, the more round body is female, and the longer body is male. The flat bottom plate is female, and the concave is male. The short tail is female, and the long tail is male.

In order to avoid slipping off the female shell during mating, the abdominal carapace of the male turtle is slightly concave, which can just catch the protruding dorsal shell of the female turtle; However, the female turtle does not need this structure, so the ventral carapace is flat. You can understand that you can quickly distinguish between male and female by turning the turtle over and touching the amplitude of the abdominal carapace with your fingers.

The pattern on the abdomen of the male turtle is sparse, while the pattern on the abdomen of the female turtle is dense. Female turtle, the dorsal carapace is short and wide, the ventral carapace is flat and unindented, the tail is thin and short, the base of the tail is thin, the cloaca is close to the posterior edge of the carapace, and the notch formed by the two anal shields of the ventral carapace is shallow, and the notch angle is larger.

Male turtle: the dorsal carapace is long and narrow, the ventral carapace ** is slightly inverted, the tail is thick and long, the tail base is thick, the cloaca is far from the posterior edge of the carapace, and the two anal shields of the ventral carapace form a deep notch, and the notch angle is small. Note that the male turtle becomes black when it matures, while the female turtle still has its original tan body color.

A small number of females also turn black when they mature.

<> grass tortoise. Generally, when it is 7-8 cm, it can be divided into male and female. There are many ways to divide males and females, firstly, you can look at the tail, the male turtle has a longer tail, the female turtle is thicker, and secondly, you can look at the cloaca, the female turtle is close to the edge of the abdominal carapace, and the male turtle is farther away.

In addition, those with sunken ventral carapaces are generally male, and those with flat ones are female. It should be noted that the male grass turtle will ink when it grows, while the female will not.

Here's how to tell the male and female turtles:1. Look at the body type, it is mainly used on turtles of the same age, male turtles are a little thin, and female turtles are larger.

2. Looking at the tail, generally the tail of the male is thicker and longer, and the tail of the female turtle is very thin and a little shorter.

3. Look at the nails, the tail of the male turtle is slightly longer, and the tail of the female turtle is shorter.

4. Looking at the cloacal pores, the cloaca of males is generally separated from the ventral carapace by a little distance, and the shape is square. The cloaca of the female is very close to the ventral carapace, just at the posterior edge of the ventral carapace, and inside, the shape is rounded.

5. Look at the dorsal carapace, under normal circumstances, the female tortoise carapace is very short and wide. Males are different, they have long dorsal carapaces and are somewhat narrow.

Terrapids and tortoises distinguish between male and female.
