1. Pictures of distinguishing male and female Brazilian turtles

From the above picture, we can see that there are three main points to distinguish the male and female Brazilian turtles:

1. Front paws: long for males, short for females.

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

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

2. How to distinguish male and female Brazilian turtles

1. How to distinguish male and female Brazilian turtles

Generally speaking, small juvenile turtles (individual weight 250 grams or less) is difficult to identify due to sexual immaturity. When some store managers sell young Brazilian turtles, they say that the gender can be determined based on the plastron pattern. This has absolutely no scientific basis. For turtles of the same age, female individuals are always larger than male individuals. The common male Brazilian turtle weighs up to 300 grams, and the female turtle weighs about 500 grams before reaching sexual maturity. Other turtles have different standards depending on the species.

Generally speaking, for common turtles, whether water turtles or land turtles, the gender of juvenile turtles can usually be identified by the following gender characteristics based on body shape:

Female turtles : The carapace is short and wide, the plastron is flat with no depression in the center, the tail is thin and short, the base of the tail is thin, the cloaca is close to the posterior edge of the plastron, the notch formed by the two anal shields of the plastron is shallow, and the notch angle is larger.

Male turtle: The carapace is long and narrow, the center of the plastron is slightly indented, the tail is thick and long, the base of the tail is thick, the cloaca is far away from the rear edge of the plastron, and the two pieces of the plastron are The notch formed by the anal shield is deeper and the notch angle is smaller.

2. Distinguish between male and female adult Brazilian turtles

In addition, mature individuals can be identified by the following methods:

Place the turtle's plastron upwards Use the thumb, index and middle fingers of your left hand to press the turtle's forelimbs and head into the shell respectively, and straighten the turtle's tail with your right hand. If there is a black penis sticking out of the turtle's cloacal hole, it is male; If the cloacal hole discharges bubbles or thin mucus, it is female.

For most species of adult turtles of the same age, male turtles are thinner and smaller; female turtles are rounder, thicker and larger. The specific gender identification method is:

1) Male and female can be distinguished by the position and shape of the excretion hole:? The position of the male turtle is close to the tail end, and the hole is long. ?The position of the female turtle is close to the plastron, and the hole is round.

2) The thickness of the tail, the male turtle’s tail is thicker and the female turtle’s tail is thinner and shorter.

3) Is the nail sunken? Male turtles have obvious depressions, while female turtles are flat.

4) Note that the male turtle’s body turns black after maturing, while the female turtle’s body color remains tan.

5) The patterns on the abdomen of male turtles are sparse, while the patterns on the abdomen of female turtles are dense.

6) Male individuals weigh no more than 500 grams and have longer claws on their limbs. Female individuals can weigh up to 1000-2000 grams, but their nails will be shorter than those of male turtles.
