Nature's predators, survival of the fittest, dangers are everywhere. Many creatures make a lot of sacrifices when mating in order to continue their genes as much as possible and allow the offspring of the race to reproduce smoothly.
For example, the mating method of bed bugs is to give you a "knife". Male bed bugs, when mating, will stab their reproductive organs into the stomach of females. Subsequently, the semen discharged by the male will enter the female's bloodstream, flow into the fertilized sac, and finally into the ovaries. In order to reproduce the offspring, it is enough to fight even if you are injured and bleed.
The mating style of squid is also "full of violence". For example, male Dana squid will use its beak-like mouth and sharp claws to pierce holes in the female's body and shoot semen into the wound.
Bees use life to interpret "love when you die". Any colony of bees is at the behest of the queen, especially when it comes to mating. When the queen is sexually mature, she will continue to open her tail and release sex hormones to attract patrolling males to mate. The male bee, which lands on the back of the queen, inserts its reproductive organs and injects sperm. However, when mating is complete, the queen will close the tail tightly to avoid sperm outflow, and the male will have a hard time breaking free unless the genitals are pulled out with a part of the internal organs.
However, the above mating methods, compared with the squid (An) trout (Kang), are not strange, in the living environment is extremely cruel, called the deep sea of hell mode, the trout in the long evolution, evolved a set of very brain hole and sci-fi trophic mating process.
Welcome to the 500-meter-deep seabed of the world's temperate oceans, right here, and I hope you are not intimidated by its unique and alternative appearance.
Due to its imaginative appearance, the sturgeon has been given numerous nicknames by humans, such as toadfish, stuttering fish, lanternfish, and even "sea ghost fish".
Indeed, the sturgeon is a bit like a devil floating in the depths of the sea, its conical body like a spindle, its head large and flattened, its mouth wide like a large crescent, and sharp teeth with a tip inwards growing out of it, not to mention the strangely shaped fin spines on the surface.
Despite its eccentric appearance, the trout's INTELLIGENCE and skills are not low at all, and it is one of the few creatures in nature that uses "chemical weapons" to hunt.
Why?
We can see that the head of the sturgeon has a strange forward-looking fin spine, like a fishing rod. The vesicle at the tip of this fin spine contains glandular cells that secrete photosensin. Once the glandular cells secrete the photonsin, they can be allowed to carry out a slow chemical reaction under the catalytic action of photonase to achieve the effect of luminescence.
In the dim depths of the sea, many small fish remain greatly curious about light. The trout is well aware of this characteristic of living things, burying their bodies deep in the sand, revealing glowing fin spines and luring the surrounding small fish to swim here.
When the curious little fish "bites the rod and takes the bait", the squid will quickly sprang out of the sand with a thunderous momentum, open its mouth, and swallow the small fish into its stomach.
It's too reckless, this way of hunting is too meticulous.
Thinking in other words, if I were a small fish, when I was playing with light, I suddenly saw such a terrible guy coming out from under the sand, I was not bitten to death, and I had to be scared to death.
However, the trout that is so terrible from appearance to hunting is actually female.
Good fellow, even the mother is so fierce, the male squid must not destroy the world? According to our traditional understanding, in nature, most male animals are more ferocious, ferocious, fierce than females, and how frightening males are.
Then you may not be able to accept the scene that appears in front of you, the male squid, looks like this.
Are you sure this is male sturgeon? Instead of just looking for a cub to fool me?
Of course not, compared with the female squid that grins and looks at the whole world and wants to bite, this male is really a harmless, weak and helpless, and even a little cute "fish baby".
This is the complete opposite of cognition. Why is the female responsible for the King's Landing and the king hegemonic, and the male responsible for the soft and cute, beautiful as a flower?
In fact, the reason why the trout looks so contrasting is inseparable from their unique mating method.
Can male sturgeon still mate like this?
That's right, male sturgeon want to survive, and mating is their only way out.
You know, the size and near-non-existent arsenal of male trout determine that they have no predatory ability at all.
If the male wants to survive in the deep sea surrounded by strong enemies and perpetuate his genes, the only way is to find a strong female as soon as possible, hold her thighs, and combine them.
Luckily, the male sturgeon is factory set just fine. They have a certain degree of sensory organs, which can detect the pheromones emitted by females in the vast sea, and can also observe the light of females. They also have a large liver in their bodies, which stores rations for several months, so that they don't have to worry about food.
Therefore, once the male squid is born, the whole goal of their life is only one, immediately find a female suitable for mating, hold the thick legs of the king fried, accompany the red dust together, walk dashingly, ride the horse, make the world a home, and breed the next generation and give birth to more small trout.
The weirdest thing is coming.
When the male squid goes through a lot of hardships and finds a female suitable for mating, it will quickly rush up, bite the female's body, and give the female a kiss and express good kisses.
However, the meaning of this bite is not so simple, whether poor, rich, healthy, old, even death, males will not be separated from females. Because the male's mouth will gradually stick to the female's body, the wounds that were originally bitten out will slowly heal, and the male's head, sensory organs, and internal organs will slowly degenerate until they disappear. Male sturgeon will completely become a part of the female body, after which, the female will be rich in a large amount of nutrients in the body to the male's body, to promote the male reproductive system to mature, the two sides are completely combined, become hermaphrodite organisms, with two complete sets of reproductive systems, to complete the glorious cause of breeding offspring.
In this process, the hermaphroditic sturgeon can continue to accept more males, and even let as many as seven or eight males hang on their bodies and enter the life of the happy planet together. This mode of reproduction is called sexual parasitism, also known as sexual symbiosis. Many people who do not know the mystery think that the trout is a parasite, but in fact, those are their husbands. This is probably a very peculiar symbiotic mating in nature. Finally, I would like to tell you that although the trout looks ugly, they are actually a very delicious food, and you can try it later when you have the opportunity.
