Коротка вагітність опосума | The opossum’s short pregnancy

The North American, or Virginia, opossum (*Didelphis virginiana*) has a very short gestation—about 12–13 days, not about 8. Newborns are extremely underdeveloped and make their way to the mother’s pouch after birth, where they continue developing. The source’s figure likely confuses gestation with another reproductive or developmental stage.
