This animal stays pregnant all my life without interruption
Source:On our planet is inhabited by a huge number of animals, which we from time to time telling. For example, in one of our recent articles, we have found some of them, like vampires, prefer . This time we will talk about the unusual inhabitants of Tasmania and New Guinea, are able to produce offspring throughout life. These amazing animals are so-called Wallaby (Wallabia bicolor), which are similar to kangaroos but much smaller size. These marsupials females are almost always pregnant due to the unique structure of the body.
About the amazing ability of Wallaby was described in a scientific journal . The fact that these marsupials are able to conceive a child already during pregnancy, it became known relatively recently. During observations, researchers found that a few days before the birth of a baby that Wallaby is known as a Joey, females can mate again and prepare for the next birth. And the thing is that they have three vaginas and two uteruses with their own ovaries, the oviducts and tails.
Conception during active pregnancy is a very difficult task. That's why very few mammals to date, can use this reproductive strategy — shared marsupials researcher Brandon Menzies.
The longest pregnancy in animals
Wallaby is able to carry multiple babies, but it is not happening at the same time. In the course of scientific work, scientists found that the second embryo starts to develop only after the purse which is nursed the first cub, free. The feeding can take up to nine months, but, nevertheless, it turns out that wallabies throughout his life engaged in the nurturing of offspring and feeding.
With all this, scientists believe that females sometimes may not even realize they're expecting a baby. Inside the embryo in the pouch nourished his older brother or sister, as if is dormant and hardly consumes any resources of the mother.
Female Wallaby with a baby
Unfortunately, at the moment scientists do not know exactly what females constantly give birth to cubs. Perhaps this kind of response to the conditions in which they live. At the moment the most common species of this group are swamp wallabies. As a rule, they live in thickets of various shrubs and forests, but sometimes they can be found for such open spaces, like fields.
It is Important to note that the wallabies are not the only animals that are able to constantly bear cubs. This feature is observed in hares (Lepus europaeus). As a rule, their pregnancy lasts about 45 days, but the re-conception could happen for 3-4 days before delivery. However, to say that they are pregnant throughout life, it is impossible. The fact that they breed only during certain seasons, so do the breaks.
Allawi pregnant throughout your life.
