How to distinguish male and female tortoise
As a popular pet, the gender distinction of colored tortoise has always been the focus of breeders. In the past 10 days, the discussion on the gender identification of colored tortoises has continued to rise on the Internet, especially for novices and breeders. This article will analyze the distinction techniques of male and female colored tortoises in detail based on recent hot topics and scientific methods, and provide structured data for reference.
1. The main methods for distinguishing between male and female tortoises
The gender of a colored tortoise is mainly distinguished by the following characteristics:
| feature | Public color turtle | Mother colored turtle |
|---|---|---|
| Tail shape | Long and thick, with fertility holes away from the tortoise shell | Short and thin, with fertility holes close to the tortoise shell |
| Pelvic depression | There are obvious depressions | Flat or slightly raised |
| Body size | Relatively small | Relatively large |
| Front paw nails | Long and curved | Shorter and straight |
2. Analysis of recent hot topics
In the past 10 days, the discussion on the gender identification of colored tortoises has focused on the following directions:
1.Difficulty of identification of young tortoises: Many breeders reported that the gender characteristics of young colored tortoises are not obvious, which leads to difficulty in distinguishing. Experts suggest that it is best to conduct gender identification after the body length exceeds 5 cm.
2.Different varieties: Some netizens pointed out that there are differences in gender characteristics of different varieties of colored tortoises. For example, the gender characteristics of Brazilian colored tortoises and Chinese tortoises are slightly different.
3.Gender identification errors: Some breeders mistakenly believe that the shell color of the color of the colored tortoise can distinguish gender, but in fact, the shell color has no direct relationship with gender. This misunderstanding has been corrected many times recently.
3. Scientific basis for gender identification of colored tortoises
The gender of a colored tortoise is determined by the incubation temperature, a phenomenon called temperature-dependent gender determination (TSD). Studies have shown that the temperature of colored tortoises during hatching can affect its gender development:
| Incubation temperature range | Gender tendency |
|---|---|
| Below 26°C | Mainly male |
| 26°C-30°C | Mixed Gender |
| Above 30°C | Mainly female |
This scientific discovery explains why uneven gender ratios may occur in the same litter of colored tortoises, and also provides a theoretical basis for artificial reproduction.
4. Practical skills for gender identification of colored tortoises
1.Observe the tail: The tail of the male color tortoise is long and thick, and the fertility hole is located at the end of the tail, far away from the turtle shell; the tail of the female color tortoise is shorter, and the fertility hole is close to the turtle shell.
2.Check the plastic nails: The male tortoise's plastic armor is usually sunken, which is to fix the position during mating; the female tortoise's plastic armor is flat or slightly raised.
3.Comparison of body shapes: When adults, the female tortoise is usually larger than the male tortoise, which is to accommodate more eggs.
4.Pay attention to behavioral differences: The male colored tortoise will show chasing the female turtle during the estrus period, and will also slap the water surface with the front paws.
5. Frequently Asked Questions
Q: How big is the colored turtle to distinguish gender?
A: Usually, the colored tortoise needs to be more than 5-7 cm long before its gender characteristics will be apparent. It is difficult to distinguish between turtles during the period of young turtles.
Q: Will the gender of the colored tortoise change?
A: The gender of the colored tortoise has been decided during the incubation period and will not change naturally in the later stage. But extreme environments or hormone abnormalities may lead to changes in gender characteristics.
Q: Why did my male tortoise suddenly become docile?
A: This may be caused by seasonal changes or health problems. It is recommended to check the breeding environment and the physical condition of the colored tortoise.
6. Summary
The distinction between male and female colored tortoises requires a combination of various characteristics to make judgments, especially the most reliable observation of the morphological differences between the tail and the pristine nail. Recent hot discussions also remind us that there may be slight differences between different varieties of colored tortoises, and breeders need to flexibly apply identification methods according to specific circumstances. I hope that through the structured data and detailed analysis of this article, it can help you accurately distinguish the gender of colored tortoises and provide reference for scientific breeding.
