The gestation or pregnancy period of the Red Kangaroo lasts between 6 and 7 weeks. They will most often give birth to one offspring, or joey. The baby Kangaroo is extremely small when it is born, being roughly the size of a bean. After the joey is born, it will crawl up the mother's fur to get inside of the pouch.
it grabs on with its mouth and continues to develop, often for weeks or months depending on the species. The short gestation time is due to having a yolk-type placenta in the mother marsupial. Placental mammals nourish the developing embryo using the mother's blood supply, allowing longer gestation times. Like other mammals, the marsupials are covered with hair. Mothers nurse their young â a young kangaroo may nurse even when it has grown almost to the mother's size. The only naturally occurring marsupial in the United States is the opossum, Didelphis virginiana.
