Marsupials are a very peculiar species of mammal . Unlike placental mammals, that is, those embryos that develop in an internal placenta, marsupials develop and finish growing in the masurp, which is nothing more than the external bag where the embryo lives during its development.

Due to their characteristics, marsupials have a gestation period or stage between 10 and 14 days , completing the evolutionary process within the marsupium, where the mother’s nipples are.

The female of this species has three vaginas of which two are used for the gestation process and the middle one is where the young are born, and a double uterus.

At the time of birth, the young, during a very early stage of their development, crawl on a line of saliva until they reach the pouch, where the young is attached to the mother’s nipples for a prolonged period.
