Nature sometimes creates perfect combinations, just like kangaroo , male and female sexual organs match each other, which can be said to be a pair made in heaven. However, nature sometimes "scam" in the face of a duck, for example: ducks, male ducks' penis are counterclockwise, while female ducks' sexual organs are clockwise. Everyone is familiar with kangaroos in Australia, but do you understand how kangaroos reproduce? Do you understand the superiority of a "Y" penis in reproduction? Have you heard of a female kangaroo having three vaginas and two uteruses? Next, we will take some time to talk about kangaroo mating, and there are more weird knowledge to share with you.
This is interesting to note that the male kangaroo's penis is "Y"-shaped, with a forked in the middle, and a part of the semen flows out from the channel on the left, and the other part flows out from the channel on the right. Correspondingly, the female kangaroo has 3 vaginas (2 are the paths of sperm and one is the birth canal of the kangaroo) and 2 uteruses. It can be imagined that when the kangaroo is mating, the two sperm will separate and enter two different uterus , and each strand will encounter an egg. And what role does the male kangaroo's "Y" penis play?
First point, males perform double insurance , which can increase the success rate of conception, which is of great help to both females and males. In the wild, mating is very dangerous, and kangaroos can reach twice at a time. In theory, a female kangaroo can even conceive continuously: alternately conceive in two uteruses. The first type is that males undergo double insurance, which can increase the success rate of conception, which is of great help to both females and males. In the wild, mating is very dangerous, and kangaroos can reach twice at a time. In theory, a female kangaroo can even conceive continuously: alternately conceive in two uteruses. It can be said that female kangaroos can be co-bred, the left uterus is responsible for laying eggs, and within a few days after the baby is born, the right uterus will quickly become pregnant. For example, it is like a long railway track with a fork on the road halfway, and each railway track can send passengers to a different place. Once this group of people arrives, the next group of people will be picked up and boarded again. By the same token, female kangaroos can have multiple kangaroos in their uterus, and one can even appear in the parenting bag of the kangaroos and the other can be cared in their uterus.
Second point, when the kangaroos mating, the male will hold the female from behind with his front paws. However, the kangaroo's forelimb grasping ability is not strong, and the "Y"-shaped penis can be clamped on the corresponding vagina and "fixed" the other party's vagina. In this way, the female cannot easily escape before mating, and its chance of reproduction will be greatly increased. In this way, kangaroos are also the strongest of all mammals. Just like the washing and drying machine we use every day, it can not only wash clothes, but also dry clothes, and complete them in one go.
So how do kangaroos mate? When male kangaroos are in heat, they will move closer to the females and please them. The male kangaroo would sniff back and forth on the female kangaroo's genitals and back, trying to grab its body and push it down from behind. Like most animals, males always take precedence in mating and mating.
At the beginning, the female kangaroo will be very cautious and reject the male kangaroo, and then leave. The male kangaroo will chase after the female kangaroo and occasionally fight. The whole process will take about twenty to thirty minutes. After
, due to the entanglement of male kangaroos, the female kangaroo's ability to resist has continued to weaken, and gradually recognized it. Therefore, it is also beneficial for men to pursue women and have thick skin. During mating, the male kangaroo will grab the female kangaroo from behind with the front legs and cooperate with the female kangaroo. The mating time is no more than one minute each time.
After the first round of mating, they will rest for a while and then perform the second round of mating, which can increase the chance of conception.Interestingly, after two matings, the male kangaroo seems to have fallen into "sage mode" and lose all his passion. It is now the female kangaroo's turn to smell the male's genitals and tease it.
But in fact, this is not the case with kangaroos, sometimes even more rude. When encountering a female kangaroo with strong resistance, the male kangaroo will adopt a rude "raping" method, and fierce mating will even lead to the death of the female kangaroo.
