The mechanism that female dolphins developed to protect themselves from males

Known for being one of the most intelligent animals on the planet, dolphins are fascinating creatures and a new study confirms that not only their social abilities are interesting.The recent research indicates that a species of female dolphins has developed a mechanism in their genitals to protect themselves from unsolicited advances by males.Find out how it works.

This protects female dolphins from males looking to mate

Female bottlenose dolphins have evolved to the point where they can protect themselves from fertilization by some males , according to a group of researchers at Georgetown University.

Experts have explained that certain species of marine animals have extensive vaginal folds that hinder the entry of the penis and act effectively as a reproductive barrier.

Bottlenose dolphins males form strong bonds with two or four others to defend themselves against the competitors of their females.

When a female dolphin comes into contact with that group, it does not have many options on who mates with she and may end up pairing with each other .

But researchers have discovered that bottlenose dolphins have developed a secret weapon to make the mating Be more complicated for certain males.

According to Janet Mann, a researcher at the prestigious Georgetown University in Washington DC, female dolphins of this species may not choose who they copulate with, but they can decide what sperm fertilizes your egg.

The complex vaginal structure of bottlenose dolphins allows them to make subtle movements during sexual intercourse to prevent the male from successfully fertilizing it , since the penis moves incorrectly.

Both those of the Bottlenose ends such as common porpoises have developed these vaginal folds, while common dolphin vaginas and common seals have been developed to allow males access.

The mechanism that female dolphins developed to protect themselves from males

Researcher Dara Orbach, from Dalhousie University in Canada, explained that bottlenose dolphins may seem passive, but that idea is very far from reality.

Second Orbach, observing the reproductive anatomy, it is possible to see that they have all kinds of cryptic ways to control paternity .

For the study, Orbach obtained the genitals of the cetaceans that had died of natural causes and created silicone molds of his vaginas, which revealed complicated folds and spirals.

This is an «n An unparalleled level of vaginal diversity that we did not know existed before.being erect and used computed tomography to examine how they fit in the female vaginas.

Without a doubt, some amazing features that demonstrate how wise nature is.

Superfetacion: the phenomenon that allows you to get pregnant while pregnant

It is generally believed that it is impossible to get pregnant when, in fact, you are pregnant.However, Superfetacion arrives to prove that this is not quite true. Stay and we will tell you ! Superfetacion: the phenomenon that allows you to get pregnant while pregnant As you have read it: it is perfectly possible-although really very unlikely-to get pregnant when you are already pregnant.All this happens thanks to a phenomenon called "Superfetacion", which occurs when twins are conceived several days or weeks apart, the result of two separate ovulations and can be from two different parents or the same father, happening the fertilization of the second after the first has already been implanted. The superfetacion process is commonly found in several animal species such as sheep, horses or rodents. However , in humans it happens only in exceptional cases.

We tell you these signs that could indicate a possible codependence. Signals that you are codependent You give more than you receive When we talk about couples, we build the concept of two people who voluntarily decide to work in tandem to keep love afloat .Both ensure that each one feels in harmony with the connection they have built.The romantic companions will do their part to continue strengthening the emotional bond between the two, attending to the emotional needs alike. Instead a codependent person will settle for a unilateral relationship, in which only one person is willing to do whatever it takes, to give whatever he can to neglect himself, so that he can r...

"Are we not well like that?" I often reproach you. Let's give another example: you may have the classic friend who never seems to finish his studies.It is easy to be an "eternal" university student who faces the responsibilities and anxieties of the working world. And what about people who spend all their time in front of a computer screen letting out "real life" ? Sometimes, it is much easier to let ourselves go, evading responsibilities, than to put means t...

How long is love?

How long does love last? The eternal question of those who are in love.Does love last for a lifetime? Does it last 2, 4, 7 years? How long does love last for us? According to anthropologist Helen Fisher love comes to last for some 4 years .Just that first period of infatuation in which the sexual attraction is very important and in which at the end, touching the 4 years, there is offspring., then, in the second phase which is the carino , in which together we raise and educate, and in which that initial sensation fades away.Finally, comes the desire for separation.And, According to this anthropologist, this process is natural, since our organism cannot bear for a long time the ferris wheel of sensations that we feel, due to the chemistry that is generated when we fall in love : the high levels of dopamine, testosterone and norepinephrine that our brain secretes.That is why they have an expiration date: between 1 and 4 years!

What is acid rain?

Many times we have heard the term " acid rain " and generally relate it to the weather and possible contamination, but do you really know what it is? In Science Daily Online we explain it below. What is acid rain? The so-called acid rain is a atmospheric phenomenon that originates when acidic compounds are incorporated into the small droplets of water that make up the clouds.It is one of the main consequences related to air pollution that we all breathe the days. This is a cycle that starts at the moment that industries, factory smoke or car engines emit sulfur oxides in the gaseous state that is transported through the winds to hundreds of kilometers.By burning different kinds of fuels considerable amounts of chemicals are released, which not only contain visible particles of gray color, but also have a wide variety of gases not visible, but very harmful for the environment . Acidity values In the troposphere , one of the layers that make up the at...
