Creatures in nature are passed down from generation to generation for the purpose of reproduction. I don't know if you have ever seen "Parasitic Beast", whether it is a movie or an anime is quite classic. Finally the alien creatures penetrated: species that have no reproductive ability have no advantage in survival. Reproduction is really important for species. Even hermaphrodite animals need two to complete the exchange of germ cells. Most species still need to have male and female pairs, so that germ cells can be fused to reproduce the next generation. Obviously, our turtles also have male and female, so if they want to have the next generation, they must have male and female mating, otherwise only empty eggs will fall to the ground.
I believe that many turtle friends found that their turtles had begun to lay eggs when they were breeding, and only then did they realize that the "girl" had grown up and wanted to find a "son-in-law". But often at this time you will find that it is so difficult to find a matching male? Of course, here is also to see the variety, such as grass turtle, Brazil, flower turtle, flame, nanshi and other common species, male turtles are still more. In particular, the ink turtle is still specially bred, after all, the ink turtle itself is a selling point.
Take the common egg turtles such as razors and musk, male turtles are relatively few, it is not easy to look at one, the price is much higher, the things are rare and expensive, there is no way. For most species, male turtles are more expensive than female turtles. Many species of rare closed-shell turtles are also difficult to find, such as three-line closed-shell turtles and gold-headed closed-shell turtles.
If you can't find a suitable male turtle, do you have to keep one yourself? After all, some male turtles also belong to the downhill, and after returning, they may not be able to work, eat grain, and also face the problem of maintenance. Raising a male turtle yourself will take a few more years to wait for it to mature, which is costly. For us lovers, this is fine, it is all about experiencing the fun of breeding. The point is that the tortoise seedling cannot distinguish between male and female, how can you be sure that it is male? It's a puzzle! Sometimes we choose to fight and gamble once.
How to Bo? We know that most reptiles, their sex is not determined by chromosomes, as mammals do, but by the temperature at which the eggs hatch. In the early stage of incubation, the proportion of low temperature male and female is high, the intermediate temperature is balanced between male and female, and the proportion of high temperature female is high. For example, for grass turtles, the temperature when hatching is 26-27 ° C, the probability of male is high, the male and female balance is about 28 ° C, and the probability of getting a female is high at 30 ° C. Therefore, many turtle friends will choose to buy tail seedlings, and the temperature of hatching will be lower at this time to bo a male turtle. If you incubate yourself, you can choose some low-temperature orientations for incubation.
But in fact, not all varieties are in accordance with the low temperature male, high temperature mother more, this still needs to be further explored by everyone to do ah, ha ha. Moreover, depending on our geographical location, it will vary.
The reason why there are many female turtles on the market is that I personally feel that it is not unrelated to the high temperature incubation of merchants. The high temperature ensures the emergence rate and accelerates the shelling speed of the turtle, which is of great significance for them to seize the market opportunity. We will find that sometimes the season is not at all, and the seedlings are already listed, grabbing the first-hand transaction.
And often such a heating and fast hatching of seedlings, the physique is not good, many also hit the confidence of turtle friends, feel that the seedlings are difficult to raise. In fact, we may have been "recruited" in the first place.
However, there are quite a few helmeted male turtles seen on the market, almost all of them come in from outside, haha, I don't know what this situation is. Turtle friends who know can solve it.
