In the animal world, there is such a strange behavior. They will smell each other's butt before mating. Even when playing, they will sniff each other's butt from time to time.
Different states of butt sniffing between dogs
Behind the seemingly meaningless behavior, there is actually real science hidden. After reading it, I really gained knowledge.
Smell it
In our opinion, the butt is a private part. Not to mention smelling it, even leaning your head over it will arouse disgust on both sides.
What animals do is related to their desire to obtain information about each other.
Take the dogs we are most familiar with as an example. They smell the butts of other dogs in order to know the gender, personality, status, etc. of the other dog, and to judge in their minds whether they want to be friends with the other dog.
When the estrus period comes, a large amount of hormones will be secreted under the dog’s buttocks. This smell smells very pungent and stinky to us.
However, this is a good aphrodisiac for dogs of the opposite sex.
Dogs: This smells right.
Especially male dogs, they like to smell the smell of estrogen secreted from the buttocks of the opposite sex.
Not only that, male dogs can use this smell to judge whether the other party is in estrus so that they can mate with the other party.
Giraffes in nature are the best example. Male giraffes will find a favorite mating partner before the estrus period and spend the rest of the time with the female. During
, the male giraffe will sniff the female's butt from time to time, checking whether the other party is in estrus, and once there are relevant signs, mating can begin.
Giraffes can even accurately determine when a female will go into estrus through the smell of her butt, which is very magical.
Giraffe’s natural skills
In the same way, many animals in nature use the buttocks of the opposite sex to determine the signals of the opposite sex’s estrus.
Over time, I developed the habit of sniffing buttocks.
For some specific animals, smelling before mating can also determine whether the other party is the one you like.
Because dogs can use the signals transmitted by their butts to judge the other person’s diet, that is, the other person’s living conditions, physical health, and other information.
After multi-level comprehensive analysis to judge the opponent, a healthy, living condition male is naturally the best choice for the female.
Have you ever seen dogs sniffing each other’s butts?
On the contrary, they will be eliminated by the females and will not be able to complete the mission of reproducing offspring.
Compared with selecting a target based on appearance or other relevant information, the information obtained by this judgment method is very real and effective, and has become one of the important means for females to choose a mate in the animal kingdom.
You often see in science and education channel that a lioness in estrus will smell around the butt of a male lion. This is the reason.
There are also some species that are more peculiar. Smelling buttocks has become a daily communication and even a way for to say hello to . The most famous ones of
are wildebeest . When they meet, they will smell each other to judge each other's living status.
This is the wildebeest
It’s like when we meet, we always ask, “Did you eat? What did you eat?”.
If wildebeests show hostility, they will secrete mucus in their buttocks that has a pungent smell that is different from hormones. Wildebeests that smell the smell will generally walk away subconsciously, otherwise a fight will inevitably occur. This magical communication method of
needs to be completed by two means.
True Science
First, in the buttocks of animals, there are anal glands that secrete information, and the anal glands are subdivided into a variety of information glands, which transmit different signals.
Anal gland location
In estrus, apocrine sweat gland plays a leading role. The viscous liquid it secretes is an excellent "perfume" to attract the opposite sex.
In addition, what the owner of the anus eats and the condition of its internal organs can all be conveyed through the odor emitted by the anus.
Of course, just having information is not enough. There must be an excellent information collection device , and this device is usually the nose of animals.
As we all know, dogs have very good noses and can distinguish different smells.
In order to prevent getting lost, dogs will sprinkle their own urine along the route. When returning, they only need to follow the smell of urine to get home.
The reason why a dog’s nose is so developed is closely related to the olfactory cells in its nasal cavity.
The reason why dogs have a sensitive sense of smell
Data show that there are approximately more than 200 million olfactory cells in the nasal cavity of dogs, while humans only have a few million olfactory cells.
These cells collect various tiny odors in the air and deliver them to the brain's olfactory processing system.
The olfactory processing system of the dog's brain is also extremely developed, occupying a considerable part of the brain.
The two organs work in coordination and quickly analyze the smell of the outside world very thoroughly, and they can extract information from these smells.
Humans also have a similar olfactory processing system. For example, when people smell a bad smell, their brains will generate disgust and avoid it subconsciously.
The position responsible for the sense of smell
However, the human olfactory processing system is not very developed. When encountering the complex smell of , it falls into a "short circuit".
It is worth mentioning that not all animals rely on their noses to process information emanating from each other's anuses.
snake is one of the most typical ones.
Although the snake has a nose, it does not play a practical role. It mainly relies on its tongue to obtain the information it wants.
Therefore, when a snake needs to mate, it will probe its tongue near the other person's anus to collect information and conduct feedback analysis.
Snakes sense the outside world through their tongues
In order to better sense each other's estrus state, some animals will even lick them directly! It's uncomfortable to watch.
Of course, smelling the other person's anus is not only related to information, but also some animals regard it as a symbol of surrender. The hyena , the second brother of Africa, is a good example.
Among the hyenas group, the hierarchy is very strict, with female hyenas having the highest status.
Hyena family
Every adult male hyena will smell and lick near the anus of the leader female to express his submission.
New hyenas joining the group will also undergo this ritual baptism.
As a surrender, after going through the ceremony, they will also be very obedient, do the dirtiest and most tiring work among the tribe, and enjoy the lowest treatment.
The hyena feels bitter
It can be seen that behind the smell, there is hidden the wisdom and scientific truth of the animals. After reading it, people can't help but admire the wonder of animals in nature.
So besides smelling the anus, what other amazing behaviors do animals do?
The strange behaviors of animals
The first is the famous soft rice king in nature, the male anglerfish .
After a male anglerfish has the ability to act independently, the first thing it has to do is to find a parasitic female and stay with it for the rest of its life.
Male anglerfish are parasitic
Because they live in the deep sea, where there is no sunlight all year round, it is very difficult to find the opposite sex when they are in estrus. In addition, male anglerfish are small and cannot feed themselves, so they can only rely on female anglerfish to deliver nutrients to themselves.
The male parasitizing the female can also provide sperm cells , allowing both parties to complete the task of reproducing offspring. The female anglerfish is not disgusted with this state.
looks like an angler fish eating soft rice, but in fact, there is a law behind the survival of species and .After
comes the quoll. The mating time of the quoll is very long, ranging from a few hours to a day. Many male quolls die from overwork.
This guy is a quoll
This is because the number of sperm cells produced by male quolls each time is very small. Only through repeated mating can the sperm and egg cells be fully combined to complete the task of reproduction.
All kinds of nature add color to our lives and allow us to see unusual truths. We have enough reasons to protect the natural world.
