When crocodiles are sexually mature, they mate and lay eggs at the right breeding time. Generally speaking, from December to March, it is the peak period of crocodile breeding. The process of mating takes place in the water. Male crocodiles will first woo females by roaring and other means, then approach females and mate with them with their penises. About 10 days after mating, the female will lay eggs. The process of laying eggs is done on the ground, and the female will dig a hole in the ground before laying eggs, and then lay eggs in it. The hatching of crocodile eggs is also done in the pit.
As mentioned above, female crocodiles dig pits before laying eggs, and lay eggs in the pits. The hatching of crocodile eggs is also completed in the pit. It takes a long time to hatch naturally, generally at least two months, sometimes even three months. Although this period of incubation time is relatively long, but the female crocodile will always be on the side, until you hear the voice of the baby crocodile, the female crocodile will help the baby crocodile climb out of the pit, the breeding process is over. However, the success rate of natural incubation is not particularly high, only about 40%.
If artificial incubation, the time can be shortened, and the success rate of incubation is also high, sometimes up to about 90%. In artificial incubation, temperature and humidity control are two important tasks. Especially the temperature, the appropriate temperature can shorten the incubation time. In addition, the specific temperature will also affect the hatching of male and female crocodiles. If the temperature is 28-31 degrees, the hatching is female; Hatching above 31 degrees will produce a male. In addition, the position of artificial incubation is also very important, and the small crocodiles in the eggs are very sensitive to the change of position. In the process of hatching, their position can not be changed too much.
