The ultimate goal of "love" is to reproduce the next generation. At first glance, it may have shattered many people's view of love, but in fact, from humans to various animals, the first thing to do with "love" is indeed to reproduce offspring. This is not a dirty idea, nor is it a dirty thing, but the instinct of all animals.
In order to reproduce the next generation, many animals are even willing to sacrifice themselves. For example, the male squid fish gave up itself, and the male red-backed spider sticks out his butt and sends himself to the female spider's mouth. The male mantis is also likely to be eaten by the female mantis after the incident.

There are gland cells in the lantern that can secrete light. Under the action of light enzyme, light can interact with oxygen and emit light. Predation is carried out with the help of deep-sea fish.
There are 4 genera and 25 species of fish in the world, and there is a kind of cystacean fish. In order to reproduce offspring, the male fish directly gave up on themselves. The female fish of cystacean can grow to 1-1.2 meters, while the male fish is only 8-16 cm. Although the huge body shape difference is destined to be unable to mate and reproduce offspring normally, they have their own unique way of reproduction.

Once the eggs of the stinger stinger stinger stinger will begin to look for their love, and after finding them, it will cover the female fish. Over time, the lips and inner sides of the male fish gradually merge with the female fish's skin. male fish is like an parasite living on the female fish. After "parasiticism", except for the stinger tissue of the male fish, all other organs will stop developing. The male fish relies on the blood of the female fish to maintain life, and the mating of the two is also accomplished by blood circulation.
Originally, male squid fish also had the possibility of growing to 1 meter, but in order to adapt to the marine environment and to reproduce the next generation, male squid fish gave up on itself directly.
Red-backed spider delivers itself as food to his mouth
Although the male schizophrenia fish has given up on itself, it is at least an individual and can still live in vain. The red-backed spider can really be said to pay every price to reproduce.
Scientists have found that clearly knows that it may be eaten, but the male red-backed spider will still send itself to the mouth of the female red-backed spider, with a spirit of dedication to "come, eat it". Of course, the female red-backed spider also refused everyone and accepted the food on the plate. The male spider uses the gap between the female spider eating itself to complete the mating process, because the female spider will not immediately look for other male red-backed spiders after "feeding", which gives the male spider more time to complete the fertilization process.
Research found that the offspring left by red-backed spiders at the cost of life is about 40% more than male spiders who are reluctant to sacrifice themselves.
Mantis kill each other
In the animal world, in order to compete for food, seize territory, and fight for spouse rights, they will fight and kill each other. The mantis' self-killing is a bit different because they often kill their own "husband".
I believe many friends have seen a big mantis grabbing a small mantis and chewing. The big mantis' belly is obviously bigger than the belly of the little mantis. This is not to bully the small by the big, but to eat the male mantis. Then why did the female mantis eat her "husband"? Some scientists believe that it is because the male mantis has a certain substance in the body, which can allow the female mantis to produce more eggs and is more conducive to the reproduction of offspring.
Although after comparison, whether or not a female mantis eats a male mantis has no effect on its own number of egg layings, this statement is not valid, but it is not false that female mantis eats a male mantis to help reproduce offspring.
Although mantis has strong ability to catch prey, as a carnivorous insect, it is naturally not as simple as the food of herbivorous insects. Therefore, in most cases, mantis is in a semi-hungry or hungry state. Mating is a physically consuming task. Some hungry female mantis can turn around and catch male mantis after mating. This kind of food that is right at the mouth is much simpler than looking for food everywhere.
In the insect world, one important indicator of whether an animal can become its own prey is body shape. If you have a larger body shape, you can catch more prey. Female mantis shoulders the heavy responsibility of reproduction of offspring, so they need a larger body size. Furthermore, in order to find the object of breeding offspring, the male mantis needs to travel a long distance. The smaller size allows the male mantis to fly, making it relatively easier to find the male mantis.
The female mantis is a circle larger than the male mantis, and the male mantis is the "food" delivered to the mouth. It is useless to not eat it. When the mating or half of mating is completed, the hungry female mantis will eat the female mantis.
Not all female mantis will eat male mantis. Whether to eat or not depends mainly on their hunger state. Some scientists divided mantis into three groups. The hunger time of different groups was different. Some let the mantis just eat full, some hungry for 3-5 days, and some hungry for 5-11 days. It turned out that the full female mantis had no intention of eating male mantis at all. The female mantis who had been hungry for more than 5 days did not give male mantis a chance to mate, and they treated the male mantis as prey and wanted to eat it.
Although male mantis is one size smaller, they are male after all and have blood, so sometimes they will resist. Nathan Burke and Gregory Hallwell of the University of Auckland in New Zealand said in an article published by Nathan Burke and Gregory Hallwell of the University of Auckland in New Zealand said that in order to mating and avoid being eaten, some male mantis will fight with female mantis, and sometimes seriously injure the latter. But most of the time, due to the huge difference in body shapes, the male mantis ended up in failure and was eaten. However, even if it is eaten, it must complete its final mission. Studies have found that even if the head of the male mantis is eaten, their abdomen can still continue to transport sperm to the female mantis' body to complete the work of fertilization and reproduction of offspring.
For animals like mantis and red-backed spiders, whether they will be eaten may not be within the scope of male animals' thinking. They are more concerned about reproductive offspring. After all, they do not have human thinking, nor do they have ethical concepts such as family and spouse. They are all just the instinct of reproductive offspring. All the sacrifices they make are just to reproduce offspring. After all, animals like mantis only have 6-8 months of life. Even if they are not eaten, they will only live a few more months. Being eaten can make the female mantis live better and reproduce offspring better.
