At what age can the sex of turtles be determined?
A male and a female can be reliably determined only when the turtles reach reproductive age. And this usually happens at six. eight years. During this period, some external symptoms change in turtles. For example, by this age the shell of a red-eared turtle should reach at least ten centimeters in diameter.
And if you want to get a younger individual, then how to distinguish a turtle-boy from a girl? At the age of two, of course, gender can also be determined. This will help a thorough analysis of the external features of the turtles.
Helpful advice. If you are not an experienced specialist and want to get more reliable data, then consider several turtles at the same time. So it will be possible to assess the external characteristics of different representatives of the species.
So, what signs will indicate how to distinguish a turtle-boy from a girl?
Determine the gender according to the shape of the shell
Plastron (i.e. abdominal carapace) in males is concave. This allows you to stay on your girlfriend while mating. Due to the uselessness, females do not have such a feature. In girls, the tummy sometimes even protrudes, has a curved shape. Also, the baby turtles on the plastron have many small spots. In girls, they are large and rare.
The back shield (carapace) of the turtles has an elongated shape, which closer to the tail resembles a tick. In girls, the shell is more rounded.
Features of the claws. turtles
By the way, by the same criterion it is possible to determine which sex is the land tortoise. How to distinguish a boy from a girl? Everything is simple. On the forepaws of the male, long curved claws. In females, they are more rounded and shorter. Again, this feature helps the male turtle to stay on the shell of its partner during mating.
However, one must be careful with this symptom. The turtle can simply grind off its claws if it spends most of its time on the islet. Here it is worth paying attention to the material from which the sushi elements are made.
Determine the floor on the tail
How to distinguish a boy-turtle from a girl’s tail? In males it is wider and longer than in females.
Another important sign. cloaca. Since females by their nature lay eggs, for this important function you need an appropriate body structure. In females, the cesspool is larger and is closer to the shell. In males, on the contrary. The cesspool of the turtles-boys looks like a small straight line, and in girls. on an asterisk.
Pay attention to the body size of the turtles
This symptom will help in determining the gender if the turtles are the same age. Girls are larger than boys because they have an important reproductive function: they carry eggs, and later they lay.
How to distinguish a turtle-boy from a girl by behavior
Usually in wildlife, males have to compete for the right to fertilize a female. To do this, they have to dodge in every way to please and attract the attention of the chosen one of their heart. Trachemys in this matter. not an exception.
In the mating season, males become more energetic. They demonstrate their potential, arrange a variety of games. If one turtle constantly catches up with another, then we can conclude that the breeding season has begun. The boy catches up with the girl to show himself to her in all its glory. Usually, males in front of females attractively shake their heads and move their front paws.
Simultaneous comparison of several individuals and a combined analysis of all the listed characteristics will help determine the sex of the future pet. If you know how to distinguish red-eared turtles (a boy from a girl), then you can pre-select a nickname for your pet. Of course, up to puberty it is quite difficult to determine the sex of this exotic animal with accuracy. To do this, you need to be a great specialist, but, as they say, you can try your luck.
Determine the sex of the turtle by the shape of the shell
In males, the carapace has a more elongated shape, and in females it is more round.
Determine the sex of the turtle by the type of plastron
Plastron is the lower (abdominal) part of the tortoise shell. According to its structure, it is possible to determine the sex of a turtle only during its maturity. By this time, the shell of the animal grows to its normal size – about 10-11 centimeters in length. The female plastron at this time has a completely flat shape, and the male plastron in the tail region is slightly concave inward
Determine the gender of the turtle by the shape of the claws
In males, the claws are much longer than in females.
Determine the sex of the turtle by the size of the tail
In the male, the tail is longer and wider than in the females. In females, it is quite short. In this case, the tail of the male tortoise is bent down, and the female is located parallel to the plane of the bottom of the terrarium.
Determine the sex of the turtle by the location and shape of the cesspool
The cesspool of all turtles is located on the inside of the tail. The anus in the male has an elongated shape – it looks like a narrow gap and is located closer to the tip of the tail. In females, the cesspool has the shape of an asterisk and is located much higher, i.e. closer to the base of the tail.
Determine the sex of the turtle by behavior
Female turtles are usually very shy and try to keep their head drawn into the shell. Female individuals are not very active and try to sit in one place. Males are much more active and inquisitive – they like to walk, therefore they rarely hide their heads.
Trachemys tortoise is a reptile, which can often be found 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.
Fish, lizards, frogs, turtles – this 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 old 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 insemination 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 rubella based on 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.
Of course, such a definition is possible only in the case when there are several turtles and they are heterosexual.
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 who better to keep – male or female – is not important for red-eared turtles.
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).
How to distinguish the red-eared tortoise of a boy from a girl?
It will be easier to cope with this task if you compare individuals of the same age. is an inhabitant of fresh water bodies. Its decoration was a spot of bright red or different shades of yellow, located next to the eyes. Determine the sex of reptiles becomes possible from the age of one.
Some of the main differences between females and males, which even a beginner can notice:
- The size. If you compare two turtles the size of a palm, the female is significantly larger than her partner.
- Front claws. The male has longer and larger claws. During mating games, they allow you to attract female individuals by scratching their neck.
- Tail. When examining the back of the body, you can see the tail, which in boys is more dense and long.
- Behavior. Males are distinguished by aggressive behavior, unlike loving females.
- Anus location. In girls, it is located near the carapace.
- Shape and size of cesspools. Since nature has endowed the female with the ability to lay eggs, the appearance of cesspools can be compared with an asterisk. It is larger in diameter, in contrast to the opening of the male, having the shape of a longitudinal line.

Therefore, along with the acquisition of a small pet, it is advisable to arm yourself with knowledge about its species.
Aquarium turtles have long ceased to be exotic even in our parts, which, it would seem, are not intended for their habitat. However, the most popular among Russian aquarists is the red-eared turtle.

What should I do if I can’t determine the gender of the turtle?
If, after a thorough examination of the pet, you do not understand how to determine the sex of the red-eared turtles, you only have to consult a specialist or wait until the animal grows up. It is not necessary to wait 6-8 years, it is possible that closer to adolescence the external sexual characteristics of the turtle will become more pronounced.

If you plan to have only one pet, then its gender will not matter much, since there are no fundamental differences in the care of males and females. However, it is worth taking into account the fact that red-eared male turtles can behave quite aggressively both in relation to neighbors in the terrarium and to their own owners.
