MARSUPIALS AND MONOTREMES are two orders of
mammal that differ from other mammalian groups Scapula
in the ways that their young develop. The order Clavicle
Marsupalia, the pouched mammals, is made up
of kangaroos and their relatives. Typically, Humerus
Thoracic
marsupials give birth to their young at a Sternum vertebrae
very early stage of development. The
young then crawls to the mother’s Radius
pouch (which is on the outside of
her abdomen), where it attaches
itself to a nipple and remains until
Ulna
fully developed. Most marsupials live in
Australia, although the opossums—which Lumbar

are classified as marsupials despite not Carpals
having a pouch—live in the Americas. Metacarpals
The order Monotremata is made up of
Phalanges Rib
the platypus and its relatives (the echidnas,
or spiny anteaters). The monotremes are Femur Sacrum
primitive mammals that lay eggs, which the
mother incubates. The monotremes are found Caudal
only in Australia and New Guinea. vertebrae
