Are zebras marsupials?
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.

Is a polar bear a marsupial?
No. There are three types of mammals: monotremes, marsupials, and placental mammals.

A polar bear is a placental mammal.

What are three feeding adaptations of three groups of placental mammals?
Whales, dolphins, and porpoises form one group because they can swim and get sea food. The mammals in the carnivore group, (cats, dogs, otters, seals, ect.) are all predators because they have enlarged canine teeth. Primates, (monkeys, apes, humans) have large brains and eyes that face forward. Also, primates have adaptations for grasping. Hope this helps! :)

What are the three kinds of mammals?
The Monotremes, Marsupials, and the largest group, Placental Mammals.Monotremes are mammals that lay eggs. The only monotremes that are alive today are the spiny anteater, or echidna, and the platypus.Marsupial's young are born in an extremely immature state; most female marsupials have pouches. Some marsupials include the koala, kangaroo, and the numbat.Placental Mammals are the most familiar group (meaning us), but also contains a diverse group of organisms from rats to dogs to horses.
