No. Mammals are divided into three infraclasses: monotremes, marsupials, and placental mammals. A giraffe is a placental mammal. This means that the baby is born live, and that it is born developed enough that it will not have to immediately crawl onto the mother's nipple and attach itself. In fact, baby giraffes can walk seconds after being born.
Marsupial Mammals. Marsupials are the group of mammals commonly thought of as pouched mammals (like the wallaby and kangaroo at left). They give live birth, but they do not have long gestation times like placental mammals.Instead, they give birth very early and the young animal, essentially a helpless embryo, climbs from the mother's birth canal to the nipples.There.hylacinus, an extinct marsupial wolf. Though marsupials today do not have as many species as do the placental mammals, they are quite structurally diverse. They range from small four-footed forms like the marsupial mole, Notoryctes, to the large two-legged kangaroos.
