Trachemys tortoise is a reptile, quite common in home aquariums and terrariums. She is beautiful and interesting to watch. There is a lot of information on caring for such a pet. But there is one question that baffles many: “How to determine the sex of the red-eared tortoise?” This information can be interesting both simply out of curiosity and in terms of obtaining offspring.
Determining the sex of some species of fish, lizards, frogs, turtles is a rather difficult task. It is necessary not only to be very attentive, but also to know some of their physiological features. We hope that this article will help readers understand this issue.
Ideal age for sex
People buy both young and adult turtles. And at any age, there are certain structural features of the body that can be used to judge gender. But the easiest way to do this is for five to seven year olds. This is explained by the fact that red-eared turtles develop for a very long time and become sexually mature at this age. For research, experienced tortoises are advised to stock up with a ruler and a magnifying glass.
There are generalized characteristics for determining sex, universal for all types of turtles. You can judge gender by:
- eye color;
- coloring of the upper jaw;
- nose color;
- the background of the head;
- claw length and thickness;
- along the plastron, that is, the ventral side of the shell;
- in the form of the shell itself;
- along the length and thickness of the tail;
- by location and type of cesspools;
- by severity of femoral spurs;
- the size of the turtle;
- on sexual behavior (flirting, aggression, harassment, etc.).
Determination of the sex of rubella by external signs
Carefully studying the turtle, pay special attention to the main features.
Tail. This is the most common criterion among breeders. If we take two turtles and compare their appendages at the posterior end of the body, then the one with which it is longer, wider at the base and narrower to the tip, is a male. And an individual with a shorter, evenly thick and rounded tail is a female.
Plastron shape. Inside this formation, in the lower part of the abdominal shield, the genitals are located. In females, the back of the carapace has a flat surface. But in males it is modified and slightly concave. Due to this feature, the covalent can be fixed on the female at the time of mating.
Claws. An indicator is their shape and length. If the claws are short and pointed, then you have a female, and if they are long and curved, then a male. However, when determining the gender of the claws, you can be very mistaken, especially with too young or old turtles. In the former, the claws may not yet be fully formed, while in the latter, they can already be worn off the ground.
- Body size. Females are always larger than males, as they have to bear eggs.
- Shell shape. In males it is narrower and longer, while in females it is rounded and short.
- The shape of the rear end of the plastron. In males, it is V-shaped, pointed. In females, on the contrary, it is rounded.
- Anal hole. The female cesspool has the shape of an asterisk and is located at the base of the tail. The anus of the male is more like a longitudinal line and shifted to the end of the tail.
- Face shape. This feature is very controversial and not fully confirmed by zoologists. Nevertheless, it is believed that the muzzle of the muzzle is narrower than that of the female.
Behavioral sex determination
Breeders with experience claim that it is possible to identify girls and boys among the red-eared turtles on the basis of monitoring their behavior.
Females are distinguished by more calm behavior. Males actively move and taste everything around. They also clearly exhibit sexual behavior, which consists in chasing the female, nibbling her neck, nodding her head.
It is no less interesting to observe the behavior of the male during mating games. He meets a female in the water, turns his muzzle towards her and swims backwards, while, as it were, tickling the claws of his forepaws with his chin.
Now you know when and how you can determine the sex of the red-eared turtle, and you can pick up a pair. And this means that your calm and thoughtful reptiles from now on will not only adorn everyday life, but will also be able to bring offspring. If you prefer to keep one animal, rather than a pair, then you need to remember that males are more aggressive and territorial. If you want to have this pet for a child, then it is better to opt for the female representatives, because they are less conflicting and practically do not bite.
Well, in conclusion, an interesting fact: the temperature of the offspring is directly affected by the temperature established in the dwelling during the incubation period (if it is less than 27 degrees, there will be males, and if more than 30, then females).
