It is believed that except dolphins, some species of monkeys and humans, animals have sex under the influence of instinct - they find a couple only to produce offspring. This is not entirely true: some species of animals also have sex for pleasure and sometimes in a very interesting way. For instance:
1. Goats have lesbian sex
Homosexuality is not uncommon in the animal kingdom. But as far as we know, only two species of males can become aroused by observing the intercourse of females: humans and goats.
Yes, goats love to watch the goats' lesbian acts. In most cases, the goat is so excited that it tries to join them as a third partner, unless, of course, the goats chase him away.
However, for goats, lesbian sex is not entirely common: rather, it is extreme, when the goat does not show interest in a mating - thus females are attracted to him. Also, a phenomenon called urolagnia may well appear - the goats begin to urinate on each other in the hope that the goat will drink some of the urine.
By the way, in the opposite case, it does not work: male goats do not copulate with each other in the hope of attracting a female.
2. Guppy fish use their ugly relatives to look more attractive themselves
It is common practice for people to appear in public with less attractive friends, and not at all because we need to be friends with everyone, but because we are more like supermodels that way. But the same trend is observed in guppy fish.
Female guppies prefer brightly coloured males. This is understandable from the point of view of evolution: beautiful individuals are always perceived as the strongest and most prolific. Meanwhile, the ugly males can only wait.
However, the researchers noticed that the genes of the dim guppies are passed on as often as the bright ones. Such males try to stay close to even less attractive males to look much better in comparison with them. The fact that guppies adhere to this tactic is especially interesting, as it serves as an example of a possible self-awareness that most animals do not have. An ugly guppy knows about his unattractiveness, and as soon as he realizes this, he immediately goes in search of even uglier fish.
3. Tasmanian devils practice BDSM
Of course, there are many species of animals in which the male hurts the female during mating or vice versa. But Tasmanian devils practice this behaviour as a "love game" - the female pretends to be a victim, but the male rarely causes her serious injury.
However, the female will not even consider the possibility of a connection if the male does not prove his masculinity. But instead of fighting for her with other males or hunting, he pounces on the female - scratches her, bites her, hits her or even throws her on the ground. The more he does this, the more she becomes ready to mate. If the behaviour of the male does not satisfy her, they change roles, and in this case, the female already beats the male.
This is real sex. The biting and scratching foreplay can last over an hour and is repeated over and over for two days. After intercourse, the male simply falls asleep.
But the Tasmanian devil wants to make sure she has mated with the best male, and so she leaves to find herself another. She will do this over and over again until she is sure of the correctness of her choice. The devil can bear up to four puppies, each of which will have completely different fathers.
4. Albatrosses “meet” for years before mating
As you know, people can date a partner they like for a very long time - this is one of the distinctively human traits. But albatrosses behave in the same way. And if some people think that two dates are enough, albatrosses are picky creatures: since they live so long, courtship can last for years.
The reason is that each albatross has several basic movements inherent in his head, and if he and a potential mate can perform these movements together, then only then will they start creating offspring.
On average, an albatross dance takes several hours and can include complex sequences of movements: birds bow, jump, snap their beaks and touch each other. In some cases, the couple practices dance together for up to two years. This is surprising, but most often the female end up laying an egg.
And, as is the case with many human couples, once the chick emerges, the dancing stops. His father and mother raise him together, but it is believed that they managed to establish themselves as excellent partners during the courtship stage.
5. Females of centipedes can tell the male exactly how they like to mate
Sex for animals is just a way to pass on their genes, but female centipedes know a way to explain to their mate exactly what they like - and they do.
The female centipede can store the sperm of several males in her body at once, but later she chooses the sperm of only one male to produce offspring. And she chooses based on the pleasure received during intercourse.
During mating, the male enters the female with the help of his pedipalps and begins to inject sperm through them. The pedipalp is an extra limb with a penis near the spider's mouth. The female responds by stroking the male's pedipalp with her own, and the result is a sound similar to the creak of skin.
This squeak serves to ensure that the male injects the sperm into the female as she pleases the female directs it. If everything suits her, then the seed will slip into her body, and there is a great chance that this particular spider will become the father of her cubs. If he does not listen to her, then she will reject him.
6. Black vultures hate treason
No one likes traitors - people are extremely negative about those who break their promises behind their back. As for black vultures, these birds also hate deception and severely punish "Don Juan"
Black vultures form pairs for life and take monogamy extremely seriously: if a vulture tries to court a busy female, then the other vultures collectively beat him. This is because the vulture chick needs constant care, which requires the continuous attention of both parents. They incubate the egg in turn, changing every 24 hours, and in the first year of its life, they feed the chick alternately. Thus, a young vulture, caring for a strange female, puts the life of the chick in danger.
