AIDS disease strains identified sources, animal sex inventory

March 6 News, AIDS is one of the deadliest infectious diseases in human, the world still does not completely cure AIDS medical means. After years of joint research by multinational scientists, scientists have confirmed that 4 of the known strains of HIV are from chimpanzees and gorillas in Cameroon, the first time that humans have fully identified all sources of the HIV strain.

It is reported that there are 4 kinds of HIV strains known, respectively, M, N, O, P, each with different sources, of which the most widely disseminated m and N have long been confirmed from chimpanzees, but the rarer O and P have been unable to confirm the source.

By analyzing the genetic data of chimpanzees and gorillas in Cameroon and neighboring areas, the researchers finally confirmed that both O and P were gorillas from southwestern Cameroon.

The world has only two cases of P-type cases, and O-type only 100,000 people, mainly in China and the west.
As is known to all, the transmission of AIDS through the main channels of blood, mother and child and sexual behavior in three ways, and in the animal world, chaotic sexual behavior is widespread or even rampant. Same-sex, parent-child, cross-race, rape, incest, group sex and other phenomena abound, especially in some chimpanzee groups, is extremely chaotic, which to a large extent also contributed to the spread of AIDS in such groups.

1. Bonobos-fornication

In sexual life, bonobos are the most similar animals to humans.

They are the only animals that use a face-to-face mating posture to make French kissing in addition to humans. The entire community of bonobos is built on the basis of sex, and in contrast to them, the ancient Romans were like a group of men who were serious about sex.

In settling disputes, bonobos do not resort to violence, but to sex.

In addition, sex is their way of greeting each other, apologizing and asking for extra food. In the bonobo community, sex is by no means confined to the opposite sex, and they can masturbate to each other and even have sex with one another.

For mothers in the Bonobo community, they have sexual relations with any other person except their own children.
2. Hyenas--females have dildos

The female hyena has the same clitoris size and shape as the male penis, sometimes up to 7 inches (about 18 centimeters), or even like a penis;

Their labia can fit together, like a scrotum, and two adipose tissue like testicles.

Because of these characteristics, it is difficult for ordinary people to distinguish between male and female coyotes. When mating, the male wolf plugs the penis into the female's dildo (the clitoris).

For a female hyena, childbirth is a nightmare, with one-tenth dying in childbirth and the firstborn often choking during the birth of the birthing canal.

Coyotes usually produce two of a child, the competition between young cubs is very fierce, the stronger cubs tend to kill their brothers/sisters.

3. Dolphins-Violent rapists

The dolphin's penis can roll, rotate, and even scale.

Unfortunately, they naturally have an insatiable libido that can rape other animals, such as turtles, whales, and even humans.

Many times they even rape their own kind.

In the case of rape, the male dolphin ejaculate in just 12 seconds.

, fruit fly--sperm length ranked first

Do not assume that a small animal will not perform amazing sexual behavior, the scientific name Drosophila bifurca Fruit Fly is a representative.

The fruit flies are ranked first in the animal world, up to 2 inches (about 50 millimeters), and 1000 times times the size of human sperm.

Fruit flies have about 11% of the weight of their testicles.

It sounds incredible, but it's a must for a fruit fly.

The reproductive system of the female fruit flies is one of the most complex in the animal world, producing destructive chemicals that destroy fragile sperm before fertilization.

5, Red Edge belt snake--30,000 groups of sex

The mating behavior of red-edged harness snakes is one of the craziest in the animal world.

They hold a mating spree every year in Manitoba Prov., Canada, after the females wake up from hibernation. After awakening, the female snake releases a pheromone that attracts hundreds of males at a time.

Sometimes, there are more than 30,000 red-edged snakes in the mating spree, wrapped around each other, the scene is very good. Even more surprisingly, male red-edged snakes sometimes release pheromone and organise a mating spree. Scientists do not know why the male snake staged this behavior.

One theory is that the males do so in order to be warm and protective, like females during mating seasons.

6, Pipa fish-male parasitic female fish body

For years, scientists have been unable to understand why only female pipa fish were found. More bizarre, all females have a weird bump on both sides of the fish.

After research, the researchers found that these lumps were the remains of the parasitic male pipa fish. Male Pipa fish are small in size and lose their digestive system long enough to mate. Among the Photocorynus spiniceps, the males are only 0.25 inches (about 6.35 millimeters) in length, one of the smallest known vertebrates.

By contrast, females are 500,000 times times the size of males.

In order to survive, male pipa fish must find a female and parasitic on the female fish body. They bite the female, release an enzyme, dissolve the skin tissue, and then combine with the female fish.

In this way, the male's semen enters the body of the female and acquires the nutrients of the female fish. However, the males quickly die, leaving only a ball of testicles, ready to fertilize the females when they are ovulating.

Scientists have discovered female pipa fish with 8 balls of testicles. For males who do not find females, they take another approach, that is, sex change is a female and waits for the male to appear.

7, clown fish-can be denatured

If you are a clown fish, you do not have to consider gender issues at all. This gorgeous little fish is neither male nor female, but androgynous.

Clown fish live together in groups, apart from a pair of clown fish and a small number of non mating males.

Female clown fish are usually the largest, not because females develop well, but because if females are not found, the largest males in the group become females.

After that, the second largest female will become a mating male, and the remaining remains, abstinence, until the female in the pair of clown fish dies.

"Finding Nemo," as an example, if the mother was eaten by predators, Nemo's father will become a mother.
