Female marsupials have two uteruses uteri and two vaginas, which join up to form a third vagina and birth canal. Some male marsupials have a two-headed penis, which lies behind their scrotum. You can divide Australian marsupials into roughly three groups:. Dasyurids — these are the meat-eating marsupials: quolls, the Tassy devil, Tassy tiger, numbats, dunnarts, antechinus.
Peramelemorphs — these are the omnivorous marsupials: bilbies and bandicoots. Diprotodonts — these are the largely herbivorous marsupials: kangaroos, wallabies, possums, koalas, wombats, and, bizarrely, the extinct hypercarnivore the marsupial lion, a horrific carnivorous wombat. The pouch is present to protect the offspring while they suckle on the nipples, and as such, is even a fold in some species, like the pockets on a new jacket.
The answer is cuscus. Australia, Tasmania and New Guinea are home to more than 50 species of kangaroos and wallabies, known as macropods, due to the large feet of these marsupials. The largest, the red kangaroo of Australia's inland plains, can be up to six feet tall; gray kangaroos are smaller and found in woodlands.
Wallabies, medium-sized marsupials, live in a variety of habitats, including shrubs, swamps and rocky cliffs. Ground-dwelling kangaroos and wallabies get around by hopping. There are also 14 species of arboreal kangaroos, two of which, the Bennett and Lumholtz varieties, occur in Australia. Kangaroos and wallabies are herbivores that eat a variety of grasses and other vegetation. The gray-furred, tree-dwellers commonly referred to as koala bears are also marsupials.
A koala's pouch faces backward, an adaptation that enabled its burrower ancestors to dig tunnels without getting dirt in their pouches. Found in eastern and southeastern Australia, koalas live in eucalyptus trees, the leaves of which comprise their entire diet. Koalas grow to be two to three feet long and weigh between nine and 29 pounds. Most Australian marsupials live in dry scrub or desert habitat. In South America, marsupials live in forests or tropical rainforests.
Marsupials can live in any part of the forest habitat, from the trees to the forest floor where, like the wombat, they burrow underground. The Virginia opossum is the only marsupial found in North America.
Its native habitat is moist forests, although it may also be in your neighborhood! It is an important part of our environment, acting as a scavenger to clean up trash, fruit, and dead animals. If you spot one in your neighborhood at night, watch how it uses its dexterous tail and paws to get around. Some marsupials are pollinators and seed distributors.
Some control pests by eating insects and vermin. Some marsupials make habitats for other underground animals by digging their burrows or loosening up the soil. The Virginia opossum helps clean up the environment by eating carrion, rotting fruit, and other items we consider garbage.
In fact, it's often found rummaging around in garbage cans! Marsupials have different types of teeth, depending on what they eat, from bugs to other smaller mammals or birds to fruit and seeds to eucalyptus leaves. Bandicoots, Australian possums, and American opossums are omnivores.
Wombats, kangaroos, and koalas are the herbivores. The rest are either insectivores or carnivores. Marsupials usually have more incisor teeth than other mammals do. Peramelemorphs - these are the omnivorous marsupials: bilbies and bandicoots. Diprotodonts - these are the largely herbivorous marsupials: kangaroos, wallabies, possums, koalas, wombats.
