How do Brazilian turtles distinguish between male and female?

Few people like to raise turtles, especially families with elderly people. After all, turtles live for thousands of years. This means that Brazilian turtles are more popular, because Brazilian turtles are more beautiful, lively and easy to raise. Many people want to know how Brazilian turtles are divided into male and female. Today, the editor will tell you how Brazilian turtles are divided into male and female.

How do Brazilian turtles distinguish between male and female?

There are three main differences between males and females of Brazilian turtles:

1. Front claws: long for male and short for female.

2. Tail: male is thick and long, female is short.

3. Cloaca: the male is on the outside of the anal shield and the female is on the inside of the anal shield.

Discrimination between males and females of juvenile Brazilian turtles

Generally speaking, young turtles of small size (weighing less than 250 grams) are difficult to identify because of sexual immaturity. When some store managers sell young Brazilian turtles, they say that sex can be judged by belly nail patterns, which has no scientific basis at all. For turtles of the same age, females are always larger than males. The common Brazilian tortoise male tortoise weighs 300 grams, and the female tortoise weighs 500 grams. Other turtles have different standards according to different species.

In general, for common turtles, whether water turtles or tortoises, their young turtles can usually be identified by the following gender characteristics:

1. Female turtles: the dorsal armour is short and wide, the ventral nail is flat and central without depression, the tail is thin and short, the tail base is thin, the cloacal foramen is close to the posterior edge of the ventral nail, the two anal shields of the ventral nail are shallower and the notch angle is larger.

2. Male tortoise: the dorsal armour is long and narrow, the center of the ventral nail is slightly sunken, the tail is thick and long, the base of the tail is thick, the cloacal foramen is far from the posterior edge of the ventral nail, and the two anal shields of the abdominal nail form a deeper engraving and a smaller angle.

Discrimination between males and females of adult Brazilian turtles

In addition, mature individuals can be identified by the following methods: the belly nail of the tortoise is facing up, the thumb and the second middle finger of the left hand retract the forelimb and head of the tortoise into the shell, and the right hand straightens the tail of the tortoise. If there is a black penis protruding from the cloacal hole of the tortoise, it is male; if the cloacal hole of the tortoise excretes bubbles or thin mucus, it is female.

For most species of adult turtles of the same year, males are thinner and smaller. The female tortoise is round and large. The specific methods of gender identification are:

The main results are as follows: 1. The position and shape of the excretory hole can distinguish between male and female: the position of the male tortoise is close to the tail, and the hole is long. The position of the female turtle is close to the ventral armour and the hole is round.

2. For the thickness of the tail, the male tortoise is thicker and the female is thinner and shorter.

3. Whether An is sunken or not, the male tortoise has an obvious depression and the female tortoise is flat.

4. Notice that the male turtle turns black when it matures, while the female turtle is still brown.

5. The pattern on the abdomen of male tortoise is sparse, while that of female tortoise is dense.

6. The male individual weighs no more than 500 grams, the claws of the limbs are longer, and the female individual weighs up to 1000-2000 grams, but his fingernails are shorter than those of the male tortoise.
