This means they share the mamalian characteristics of being endothermic, having three middle ear bones and having mammary glands. What distinguishes marsupials from other mammals is that they give birth to undeveloped young and carry them in their pouch which contains multiple nipples and provides protection and sustenance for the young. Other characteristics are marsupials' ossified patellae are not present, the epipubic bones are present, and they have a gross lack of communication between the right and left hemispheres of their brain.Common examples are kangaroos, koalas, and possums.
