Spring has arrived, all things have been revived, and it is the season for animals to mate again.
The breeding season is a big drama every year, and in order to complete the KPIs of reproduction, they begin to carefully plan courtship, after all, most animals have a partner before they can have a baby.
However, for them, finding a partner is not an easy task, and they can be described as painstakingly trying to court.
To attract female pufferfish, males swim to the bottom and slap their fins on the bottom sand to form a very symmetrical pattern. For aesthetics, they sometimes find shells to break and fill in the recesses of the pattern.
Once the project began, the fugu spent time every day designing and modifying the pattern. Usually, it takes six to nine days to make a pattern.
Next, the male puffer fish starts waiting, and if a female likes a pattern, it finds the maker of the pattern and mates with it in the center to lay eggs.
Scientists have also found that the more ravines and the more complex the shape, the more likely it is to attract the opposite sex. And those pattern authors who do not have the appreciation of the opposite sex can only admit that they are unlucky and end up working in vain.
Australian quolls are small, pink-nosed and white spots on their backs, which are cute, but they are crazy for love.
When the breeding season comes, the Australian quoll's tiny head is almost filled with a sound, that is, "go mate".
With this thought, they will immediately set off and embark on a path of "suicide".
Why is it the path of "suicide"? In order to find a mate to mate, they must walk up to spot a female.
All male Australian quolls understand how competitive it is, so they will give up rest and sleep if they want to find females early and buy more mating time.
According to the data, the average rest time of male quolls during the breeding period is only 8%, compared to 24% for females.
One of the male quolls in the study at the University of the Sunshine Coast in Australia, Moimoi, walked 10.4 kilometers overnight in search of a mate. It is undoubtedly a very long road for this small animal.
And after a night of trekking that did not achieve the results it wanted, Moimoi did not hesitate and continued to move forward in search of all possible opportunities.
Although Moimoi was already in a very bad state due to overwork at that time, his eyes could not see clearly.
Normally male Australian quolls only live one breeding season, females can survive about four breeding seasons. So it's not too much to say that they are courting with their lives.
Sea flat worms, the appearance is quite like sea slugs, but the relationship is far behind.
The body is flat like freshly rolled dumpling wrappers, there is no respiratory and circulatory system, and there is only one small mouth to eat and excrete throughout the body.
Such a simple creature, but because of the strange courtship and mating behavior, leapt into the sight of humans.
Sea flatworms are hermaphrodites, and each sea flatworm has both male and female reproductive organs. In the animal kingdom, hermaphroditic phenomena are not uncommon, but sea flatworms will always struggle with who is the father and who is the mother in this relationship, and will fight on this issue.
Weapons are needed to fight, sea flatworms are soft all over, but you think they have no force value? They skillfully use their male reproductive organs to fight.
So in the water, two breeding sea flatworms try to penetrate each other's epidermis to complete insemination on the one hand, and on the other hand, they have to guard against the opposite genitals piercing themselves, otherwise the bearer of fertility responsibilities will become themselves.
Back and forth, it's like fencing. However, it still happens that both sides are both father and mother.
The Great Bustard is one of the largest and heaviest flying birds, eats a lot of food, and the way to courtship is also wild.
When the breeding season comes, the appearance of the male Great Bustard will change somewhat. White feathers will grow on the outside of the throat, which looks like the white beard of an elder, which has a mature and stable taste.
And their way of courting is to boldly show the "chrysanthemum" region.
When the male Great Bustard is in heat, he will raise his tail feathers upwards to look like he is holding his buttocks in order to show more white feathers.
In their courtship rules, the more and whiter the white feathers that males expose, the more they are appreciated by females.
In order to make his hair look more, the male will raise his tail feathers as high as possible to show his full strength, while also blowing up the feathers on his neck and chest to make himself look stronger.
Ready for these jobs, the male will courtship the female in such a way by dancing in circles around the female. The female will carefully examine the white feathers of the male, and if interested, the female will give her a peck in her mouth to help take care of it, indicating that the female agrees to the affair.
It can be seen that animals spend no less thought on finding objects than we humans.
Although some animals' courtship methods may seem comical to us, whether by showing themselves, building nests, playing fair, or even giving with their lives, primitive instincts drive them to try to pass on their genes to the next generation to the best of their ability.
