The world is so big, and there are all kinds of wonders. Especially the magical nature has created many magical natural landscapes and cute and unique animals. Today I will take you to take a look at the strange reproduction methods of animals in nature. Some animals can even make mating and reproduction !
1.Haihorse
Haihorse has always been a special type of Haihorse . Not to mention anything else, it looks similar to the horse on land, but there is no animal in the ocean that really treats it as a horse. What is even more peculiar is the way of reproduction of hippocampus. Under Generally speaking, animals in nature need male and female to mating . During this process, the male expels sperm into the female's body and combines with the egg cells to complete fertilization.
However, the hippocampus is an exception. It is that is spawned by the female hippocampus in and then discharged to the male to complete fertilization in the male hippocampus. This is because the males of the hippocampus have one more organ than other animals, namely the incubation sac, also known as the parenting bag .
After the female hippocampus lays eggs and is placed in the male's parenting bag, the male fertilizes the eggs in the parenting bag. After the fertilization is completed, the fertilized eggs must stay in the hippocampus dad 's parenting bag for 3 to 4 weeks until it hatchs in the parenting bag to become small hippocampus .
Finally, the male hippocampus shrinks its parenting bag and squirts out hundreds of small hippocampus directly.
2. The octopus hatched to death
The octopus is the smartest animal in the ocean . It has always attracted much attention. There was also a very famous octopus used to predict the results of football matches. However, although octopus is smart, their reproduction has always been very difficult.
is mainly because octopus will reproduce "suicidely". After the female octopus and male octopus will lay a large number of octopus eggs in the nest. Due to the nature written in their genes, the female octopus will stay in the nest to take care of its eggs, and use tentacles to move the egg sacs from time to time to prevent them from dying from hypoxia. In this process, female octopus not only needs to spend a lot of effort, but also needs to be in a hunger strike state of , because if you want to prey, you will be distracted.
After this process lasts for a week or two, the female octopus is almost exhausted, and some may even be hungry to eat their tentacles, but it still has to persist because the hatching of octopus eggs may take more than a month, so when the small octopus really hatched, most female octopus' lives will end.
3. Eat the male mantis after mating
Everyone saw the Black Cat Sheriff when they were young. In an episode, the mantis bride ate her husband. She thought it was outrageous at the time, but this is also the nature of the mantis race. After mating, in order for the females to have enough physical strength and nutrition to reproduce the next generation, they must do this.
Mantis is a dioecious insect, so it must be mated to reproduce the offspring . During mating, the male mantis will fly to the female mantis and then start mating. After mating is completed, most female mantis will eat the male mantis .
and The reason why female mantis does this is mainly for the next generation of breeding . If it eats male mantis, it can supplement nutrition and ensure smooth mating. Generally, wild mantis consume too much physical strength during mating, which may lead to mating failure. Therefore, in order to ensure that it can continue to reproduce, female mantis will prey on male mantis.
and the benefits of doing this are After the female mantis eats the male mantis, the semen in the male mantis can flow into the female mantis more quickly and ensure fertilization.
However, it is said that as long as the female mantis is provided with sufficient nutrition, it will not eat the male mantis.
4. Hermaphrodite sea slug
sea slug is also called sea rabbit . It is a veritable sea elf . It looks cute and has a beautiful color, but their breeding method is quite weird.
Sea slugs are hermaphrodites, and they can also mated with themselves, fertilized, and then reproduce offspring. The reason they can do this is because there is an egg-sperm groove between the two reproductive holes of the male and female in the body of the slugs, so they can use this channel to allow sperm and egg cells to bind directly in the body to fertilize.
However, although they can achieve such an amazing breeding method, they generally do not use this method. Most sea slugs still use allobiotic fertilization to reproduce offspring.
However, even if it is allobiotic fertilization, the way they use is very strange.
When two sea slugs are ready to mate, they will fight first, and the winning party will become male, and the other party will become female, and then mating.
But this is not over yet. After , the sea slug that has been transformed into a male will lose the male's reproductive organs, and then the roles will be exchanged to females, while the other sea slug that has been transformed into a female will become a male again, and then mating.
Although from our human perspective, it feels that their breeding method is strange enough.
However, sea slugs do not have brains and cannot think. They only rely on instinctive actions in their genes. The reason why they have to interchange roles is to fully combine sperm and egg cells, and both sea slugs can be successfully fertilized, so that more fertilized eggs can be laid, and increases the survival rate of offspring.
5. Polymer made naked mole rat .
Naked mole rats are mammal , and the reason they are called this is mainly because they are a type of Mole family, but their bodies do not have much hair. 's entire body is almost naked, and you can see the skin of the whole body , so it is named.
And because of long-term underground living, his eyes have also deteriorated. To be honest, the appearance of naked mole rats often appears in various horror movies.
However, "rats cannot behave like a person", the mouse society implements polyandry system .
There is a big female rat in each naked mole rat group, which is equivalent to the king in the tribe. There are several male rats around this king, who are specifically mating and reproducing offspring with the king rat. The other naked mole rats are called worker rats. is specifically responsible for taking care of the king and its male rats in the tribe. These worker rats, both male and female, have no reproductive ability. According to scientists, it is because they are inhibited by hormones secreted by the king rats.
6. The yellow-headed hind-jaw fish that hatched in the mouth.
Most of the fish in the ocean are still that undergoes in vitro fertilization, and basically female and male fish directly lay sperm and eggs, and throw them in place after fertilization in the water. It can be said that it is quite irresponsible.
However, The male fish in the yellow-headed hind-jawed fish is the alternative . It can be said that it does its best for its offspring.
Harminal fish is a kind of " mouth fish " , which literally means that they will use their big mouth to hatch fertilized eggs.
The female yellow-headed hindragon fish will go away directly after laying eggs, while the male yellow-headed hindragon fish will discharge sperm and bind to the eggs and fertilize them, and then put all the eggs into the mouth one by one, and then let the fertilized eggs slowly hatch in their mouths.
In this process, male yellow-headed hindragonal fish basically do not eat or drink, and this process will last about a week.
The work will come to an end until the small fish in these fertilized eggs are hatched, but these male yellow-headed hindragon fish will not leave, and will stay by the small fish for some time to take care of them.
7. bed bug
The male bed bug is a notorious "slag bug" in the animal world.
Because of them, there is another scientific name for mating between bedbugs, called " traumatic insemination ". The reason why this is called is because male bedbugs will ride on the female body when mating, and use their very sharp reproductive organs to directly penetrate the female bedbug's body, inject sperm into the female bedbug's belly, and then these sperm will slowly spread into the female's ovaries to complete fertilization .
But the reason why this behavior is traumatic is that male bed bugs will directly pierce any part of the female body, and it is mandatory, which is equivalent to directly stabbing a wound on the female body , which of course will cause huge damage to the female bed bugs.
Some female bed bugs may even die directly due to wound infection after mating, and cannot even wait for the fertilized egg to hatch.
8. turkey that can be hatched without fertilization.
When it comes to turkey, the first thing that comes to mind is a big meal on the famous foreign festival Christmas. Uh, but its sales in our country may not be very good. After all, its meat quality is a bit too tiring for us. It's too far to get back to the topic.
Do you know? Turkey can actually perform parthenogenesis !
Parthenogenesis is also called monosexual reproduction, which means that female eggs can develop into normal new individual without male fertilization. This phenomenon generally occurs in very ancient animal species. Unexpectedly, avian turkeys can do it.
and most turkeys can achieve parthenogenesis, which is a ability they evolved in harsh environments. When is lacking male turkeys in the turkey group, the eggs laid by female turkeys can directly hatch small turkeys even without fertilization.
Compared with fertilized turkeys, most of these turkeys will be weaker.
What's more amazing is that the small turkeys hatched by these unfertilized eggs of are basically male . The reason why turkeys have this ability may be to make up for the shortcomings of males in the group .
Although these animals are indeed varied in their reproduction, their ultimate goal is to improve the survival rate of offspring, and to better adapt to the environment and avoid being eliminated in this evolving nature. In general, it is very worthy of our admiration. What other animals do you think of are more bizarre reproduction? Let me tell me in the comment section.
