Such behavior may be considered disgusting. In fact, there may be some who consider it porn. However, the behavior is totally real. Scientists recently revealed that the behavior associated with the rejection of females to males.
Like humans, animals also have a "soul mate" option. Human males busy convincing female hero that he is indeed elected future husband. Animals also need to convince the female stud that he deserves to marry her.
Some species live shows to attract females and rejection or acceptance is made by the female. However, some other species do not.
On the species of birds, mammals, and insects, where fertilization takes place inside the body, the selection of mating couples sometimes invisible. In certain cases, females forced males willing dikimpoii "desperate". This is what happens to species E bilimeki.
Christian Luis Rodriguez-Enriquez and his colleagues from the Institute for Ecology in Vera Cruz, Mexico, to make observations on 74 pairs of E bilimeki. They want to know the reason why it takes sperm female flies.
The results showed, all females studied sperm are "paid" stud. Then, at least they take the majority of sperm released.
In a more detailed observation, a quarter of all females who dobservasi eject sperm from males. This means, all the seeds from the male was issued. Married males did not have a chance to get a descent.
Researchers were puzzled by the results of this research. If many females who do, it can be said that the female is a waste of time and energy to mating. Throw away the chance to have offspring, what is its purpose?
National Geographic reported, the analysis revealed that the purpose of the female scientist sperm is the seed of the males refused to marry her.
Ullidiid flies do not like the stud that is too "desperate" to marry her. They do not want males who do not know the meaning of "subtle rejection" before marriage to father offspring.
According to investigators, let males marry females because it is lazy to call the male. Sperm-rich protein then eaten after issued as compensation for workers who have been issued throughout the marriage.
Previously, researchers estimated that sperm eating behaviors associated with survival. However, that assumption is not entirely true.
In excellent condition lacked food, eating sperm can indeed make it fly species survive. However, it was not the sperm flies assure long lived species. This suggests that the sperm is not eaten as a main meal.
