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.
â¢ Marsupials include kangaroos, opossums and koalas, whereas rodents include beavers, mice, porcupines, squirrels, flying squirrels, gophers, agoutis, chinchillas, coypu, mole-rats, rats, and capybara. â¢ Rodents are found worldwide, whereas marsupials are found only in Australia and Americas.â¢ Unlike in the rodents, marsupials have their fertilized eggs surrounded by chorion and amnion membranes. â¢ Rodents possess a single pair of upper and lower chisel-like incisors, unlike the marsupials.odents are placental mammals that have a placenta to nourish the embryo though the embryonic development, which takes place in the uterus. Order Rodentia has over 2000 species of animals and represents 42% of all the living mammalian species.
