What I want to say is, speaking of creatures in nature, if you don't talk about the reproductive behavior between creatures, you are a little sorry for the amazing reproductive strategies they have evolved for this.
Moreover, mating is the most important activity of all creatures in nature besides eating and sleeping, and it is also the highlight of nature.
Why do you say that? You see, in order to live well, animals have to eat and hunt, so they have evolved various ways of hunting to improve the success rate of hunting.
These methods include faster speed, sharper vision, more deadly teeth and claws, and some masters who use poison and disguise, so nature is full of traps, and today and tomorrow are a good description of the dangerous environment in which animals live.
However, compared with the predation strategy, animals are also doing everything they can in mating and reproduction, taking this matter to the extreme and evolving a very amazing and incredible mating strategy.
For example, in sexual cannibalism, which is very typical in the insect world, mantis is the most outstanding representative. When the female is very hungry, she will catch the male and eat it after mating, which can not only solve the problem of food and clothing, but also improve the survival rate and the number of offspring.
There is also a kind of golden spider in nature. There is only one male mating with touching limbs, but after mating, it will cut off its touching limbs to block the entrance to prevent other males from courting females again.
Isn't it amazing? People practice the sunflower collection, or the sword spectrum to ward off evil spirits.
In the mammalian world, dogs around us will engage in self-locking behavior for half an hour after mating, which is also to improve the success rate of reproduction.
There are many other examples of such wonders, but compared with today's male pig's feet, all the above males have just graduated from kindergarten and are pediatricians in front of them.
Is this the one above? No, it's not. Although it looks ugly, fierce and slightly scary, she is a little sister.
This creature is called? ? ? ? There are many kinds of fish, but no matter what kind, ugliness is their biggest feature. According to their appearance, you should be able to guess this kind of deep-sea fish, which lives in the deep sea from 500 meters to 2000 meters.
The reason is very simple. In a dark environment, no one can see anyone. Who is so beautiful? Therefore, deep-sea creatures never work hard on the outside, just work together.
Maybe you are unfamiliar with this kind of deep-sea fish and think you can't see them! Then please look at the picture below:
Yes, that's it! Ugly appearance doesn't mean that people are not a delicious dish. ? ? ? Fish meat is very delicious, and the nutrition is still in place. It may have been a dead fish under your chopsticks. It's just that you didn't pay attention after steaming.
Judging from their teeth, this kind of fish is carnivorous, but don't worry, they don't like sports, and they are clumsy and mainly timid.
How does such a character prey?
They have a very labor-saving way. We know that there is no darkness in the deep sea, but people? ? ? ? Fish have a bioluminescent organ on their heads. Usually, they bury themselves in the sediment at the bottom of the sea, open their mouths wide, and then put the illuminator on their heads in their mouths.
Those small fish and shrimps with phototaxis will be automatically sent into people's mouths, which is very convenient.
But this method is also dangerous, because sometimes it attracts predators instead of food. What if? ? ? ? When the fish found that something was wrong, he quickly put his little light bulb in his mouth and turned his head and ran away.
So? ? ? ? Fish tells us a truth, the appearance is fierce, and people may still be a little cute inside.
Above? ? ? ? Fish are all females, so what about males? Are they fierce?
About males? ? ? ? Fish at first biologists thought they didn't exist because they were caught in all kinds of fish? ? ? ? There are no signs of male fish in the eyes, so researchers initially thought that this fish was a female hermaphrodite.
However, biologists found the above scene in subsequent research. A female fish was parasitized with many small things, which at first glance was thought to be an unknown kind of parasite.
But when you look closely, what surprises scientists is that these little things are actually males? ? ? ? Fish. They are very small, only 8~ 16 cm, while females can generally grow to about 1 m.
And these male fish have grown completely with the female fish, just like hanging a lot of small bacon on their bodies.
Why male? ? ? ? Fish grow like this, and parasitic on females? This is actually their amazing and incredible reproductive strategy.
The two small fish at the bottom of the picture above are females on the left? ? ? ? Fish, the male on the right? ? ? ? Fish, when they were young, they were exactly the same as each other, but they were completely different when they grew up.
The female's eyes will get smaller and smaller, and her body development will change dramatically, and she will look grotesque. But what about males? Except for the eyes, the body has basically not changed.
Due to the vast land and scarce fish in the deep sea, ? ? ? Fish don't like to live in groups, and they always like to act alone, so it is difficult for males and females to meet. In addition, deep-sea food itself is very scarce, so males? ? ? ? Fish have no advantage in living in the deep sea and lead a very miserable life.
How to change the status quo? There is only one way to marry Bai Fumei.
The female knows this truth well, so she has been looking for the female since she was born. If she is lucky enough to meet the female, then the male will bite the female and commit himself to death and never part.
Males who bite the female will give up their freedom for a meal ticket and their lives for breeding, because when they bite the female, their mouths and wounds on the female will heal and grow together completely within a week.
Since then, they have become a small pendant on Bai Fumei.
They can also transmit their genetic material to females through blood at any time. Does this kind of soft rice make your heart beat? Please don't, I hope you will exercise restraint.
Because the male's nutrition comes from the female, after all, the energy supply is limited, so in the end, all the organs in the male body will degenerate, leaving only the reproductive system at work, and turning himself into a "Tintin" in the female body.
Moreover, as a rich and beautiful woman, it doesn't matter if she has more pendants on her body. So we often find a lot of small bacon on females.
To be honest, this is the most wonderful reproductive strategy I have ever seen and heard. Life lies in males? ? ? ? The fish is nothing. It has been delivering diced fish for thousands of miles since it was born.
This sometimes makes me wonder, what is life? What is the significance of a life process like a male fish? Nature is really puzzling!
