A few months ago we brought you these amazing facts Animals, thus reminding us that certain creatures could adopt behaviors at least atypical. And the fact is that under these behaviors many practices are related reproduction can come as a surprise to us humans. Indeed, nature is full of fascinating examples that prove that evolution has allowed each species to find different strategies, with the main objective of ensuring the survival of their species. This form of natural selection thus offers a broad spectrum sexual practices, one more original than the other. So here’s a look at these animals that are unexpectedly reproducing.
1) Anglerfish from the abyss
Also known as Melanocetidae (or Melanocetidae) these fish live at a depth of between 300 and 500 meters. They are an excellent example of sexual dimorphism, in the sense that the male and female have features that distinguish them very easily. The females are the ones most commonly known to the general public, characterized by their luminous organ located above their jaws. But males also have their own peculiarities. Aside from being around five to six times smaller than females, if a male encounters one of them, he will bite them, thus clinging to their body. Without ever opening his jaw, the man’s tissues and blood system will eventually merge with the woman’s.and in the process loses all organs considered useless, such as eyes and fins. What remains is a kind of sac filled with spermatozoa, which the female can dispose of to lay eggs.
2) The Zeus Bug
Under his real name Phoreticovelia disparataThese bugs belong to the Veliidae (or Veliidae) family and are semi-aquatic predatory insects endemic to Australia. Commonly referred to as the Zeus beetle, this name finds its origin in Greek mythologywhen Zeus supposedly swallowed his first wife, an ocean idea named Metis. They were so named because of the male’s parasitism, in the sense that the latter, smaller than the female, perches on the back of its companion. So he will be able to be transported for several weeks while being fed a substance secreted by the female’s back. This substance comes from a pair of dorsal glands that appear before the female reaches sexual maturity. The males therefore have a habit of perching as soon as these glands appear and will not move once in place..
3) Carola’s bird of paradise
Birds-of-paradise from New Guinea are particularly known for the courtship display of the males to seduce women, which can turn out to be extremely complex. And among all the birds of paradise on the island, Carola’s bird of paradise (Parotia carolae) is considered the most complex seduction ritual of all trees of paradise. An American ornithologist would thus have identified almost 58 dance elements, all arranged in 20 different sequences.
4) Red-billed Alecto
It continues with the birds, this time with the Bubalornis niger, better known as Red-billed Alecto. The males of this species of passerine, belonging to the passerine family ploceids, have the peculiarity of having a pseudo-penis, where most birds are completely free of it. However, this pseudo-phallus has no blood vessels and does not carry sperm, and the fact is that it does not even have an opening. So it seems so The role of this member is intended only to bring joy to his partnersthe females prefer the males with a longer organ than the others.
5) Laughing Seagull
Further proof that there are all kinds of sexual practices in nature, It is estimated that nearly 20% of male black-headed gulls engage in homosexual practices. During the breeding season, these same-sex couples may have to care for the eggs that no longer have parents, which may result in some eggs escaping a tragic fate. But since nothing is immutable, it is entirely possible that these males will decide to form a pair with a female the following season.
6) Drosophila bifurca
This small fly of the Diptera family, native to Mexico and the United States, has the main peculiarity of producing sperm that can grow up to six centimeters in size, while the males barely measure a few millimeters. This peculiarity leads to others, namely that during copulation the sperm are present in a particular genital structure that allows their individualization, rolling them up like a ball of yarn before being ejected one by one into the female.
7) The Black Jacana
A real proof that not only the females have the exclusive right to raise young animals, Found in South America, these birds decided that it was up to the male to ensure descent. Here the females fight among themselves for the favor of the males. Once they have laid their eggs, the males take care of incubation, but also postpartum upbringing. On the female side, after being fertilized by a male and laying eggs, they will be in search of a new male and so on.
This primate species, endemic to the Democratic Republic of the Congo, is known to have a social organization that uses sexual relationships as a means of conflict resolution within the group. And the fact is, sex occupies a fundamental place in the organization of their society., which can contribute to the resolution of conflicts, but also to the establishment of social bonds. Bonobos therefore have a very free sexuality and often have sex without the desire to reproduce. Studies suggest that nearly three quarters of sex between bonobos is non-reproductivebut rather sociable, then called “friendly sex”.
