Pouch of Marsupial Mammals
The koala has strong claws to help it hold on to branches as it climbs in search of food.
Is a Koala Bear Really a Kind of Bear?
No, it’s a marsupial like a kangaroo and not related to bears at all. Koalas live in Australia in eucalyptus forests. They feed almost entirely eucalyptus leaves, preferring those only a few species. A baby koala spends its first six or seven months in the pouch and then rides on it’s mother’s back until it is able to fend for itself. A baby measures around 0.75 inches (2 cm) and weighs around 0.2 ounces (6 g) at birth, but when fully grown the average koala measures about 30 inches (78 cm) long and weighs up to 24 pounds (11 kg).
A koala eats between seven and eighteen ounces (200—500 g) of eucalyptus leaves a day. The leaves do not provide much energy, but koalas are slow-moving and sleep up to 20 hours a day.
For red kangaroo in the eastern part of its range, the female red deer is bluish gray rather than red.
Inside the Pouch of Female Kangaroo
At birth, kangaroos are very tiny and underdeveloped. They measure about 0.75 inch (2 cm) long when born. The female kangaroo has a pouch so that its young complete their development in safety. The newborn crawls up to the pouch by itself and starts to suckle on one of the nipples inside the pouch. A young kangaroo, or joey, stays in the pouch until it weights about 20 pounds (9 kg). Pouch animals like kangaroos are called marsupials.
Record shows of how fast do kangaroos move. A kangaroo bounds along on its strong back legs at up to 31 mph (50 km/h). It can cover about 44 feet (13.5 m) in one giant bound.
Kangaroos eat grass and the leaves of low-growing plants, just like deer and antelopes do in the northern hemisphere.
There are more than 50 different species of kangaroo and wallaby. All live in Australia or New Guinea. The red kangaroo, which weighs about 200 pounds (90 kg), is the largest, and the tiny musky rat kangaroo weighing only 1.2 pounds (0.5 kg), is the smallest.
It’s All About Marsupials
Most of the 260 or so species of marsupials live in Australia and New Guinea, but there are about 80 species of marsupial opossum in South America. One of these also lives in Nort America.
Most female marsupials have a pouch, but not all. Some very small marsupials such as the shrew opossums of South America do not have a pouch. Others, such as the American opossums, simply have flaps of skin around the nipples and not a full pouch. The tiny young cling on to the nipples.
The water opossum of South America is an excellent swimmer and has webbed back feet. Strong muscles keep its pouch closed when the opossum is in water.
Different Kinds of Marsupials.
We already aware of koalas and kangaroos, they have similarities. Physical attributes that are related to each other. Now, lets check other animals that known as marsupial.
The Tasmanian Devil is the largest of the carnivores, or flesh-eating marsupials. It is about 36 inches (90 cm) long, including its tail, and has sharp teeth and strong jaws. The devil feeds mostly on carrion—the flesh of animals that already dead—but it does not kill prey such as sheep and birds.
Bandicoots are groups of small marsupials that live in Australia and New Guinea. Most have short legs, rounded bodies, and long-pointed noses. They have strong claws, which they use to dig for insects and plant food.
A wombat is a small bearlike marsupial with a heavy body and short, strong legs. It digs borrows to shelter in and feeds mostly on grass. Its pouch opens to the rear so that it does not fill up with soil when the wombat is burrowing.
Is Platypus a Marsupial?
No, the platypus is not a marsupial, but it is an unusual animals and it does live in Australia. Unlike most mammals, which give birth to live young, the platypus lays eggs. The mother leaves her two to four eggs to incubate in a burrow for up to ten days. When they hatch, the young suck milk from the mother from special mammary hairs.
Marsupials Cool Facts
The smallest marsupials are the mouselike ningauis, which live in Australia. These little creatures are only about 2 inches (5 cm) long and can weighs as little as 0.1 ounces (2.8 g). They feed on insects.
