How do marsupials differ from all other mammals with respect to carrying unborn young?
With regard to carrying unborn young, marsupials have a very short gestation period compared to that of placental mammals of similar size. For example, a quoll has a gestation period of 21 days. It is often compared in size to a cat, which has a gestation period of 63-65 days. A wallaby's gestation period averages 30 days; a similar-sized dog has a gestation period of up to 65 days, depending on the breed. The shorter gestation period of marsupials is because they have a yolk-like placenta by which to nourish the young. By contrast, the placenta of placental mammals, or eutherians, nourishes the developing embryo using the mother's blood supply. This allows for longer gestation time.
