Bandicoots and Bilbies
Commonly known as marsupials, members are divided into seven orders; Didelphimorphia, Paucituberculata, Microbiotheria, Dasyuromorphia, Peramelemorphia, Notoryctemorphia, and Diprotodontia. the members of the order Marsupialia are pouch-bearing mammals who give birth to underdeveloped offspring. These offspring complete their development within the mother's pouch, sucking milk there. There is great diversity within this order. Forms range from the carnivorous Tasmanian wolf and Australian bandicoot to the herbivorous brushtail possum and red kangaroo. marsupials vary in size from the 1/3 ounce marsupial mole to the 155 pound gray kangaroo.
The skull of a marsupial can normally be recognized by the extra number of teeth. Tooth counts range from 40 to 50 exceeding that a most placental mammals.
The order of marsupials, Peramelemorphia, includes 2 families, the Peramelidae (bandicoots and bilbies) and Peroryctidae (spiny bandicoots, mouse bandicoot). Peramelemorphs are terrestrial animals of small to medium size. They have long pointed heads and compact bodies. Their forearms are short and and their hindlimbs relatively long. The forefeet of most species are adapted for digging, with long forefeet and strong claws on second, third, and fourth toes.
