What animal family is kangaroo?

Question 1: What subject does kangaroo belong to? Kangaroos belong to the Kangaroo family and have two front teeth.

Question 2: Do kangaroos belong to mice? Kangaroos in Australia and opossums in America both look like mice, and their names are also "mice". But they are not rats. What's going on here? Let's talk about kangaroos first Kangaroo is a specialty of Australia and a national treasure of Australia. Their biggest feature is that there is a "bag" for raising children on their chests. Kangaroo's front and rear limbs are not consistent, the first two limbs are small, the latter two limbs are particularly developed, and they jump when walking. There are more than 50 kinds of kangaroos, which are as big as goats and weigh about sixty or seventy kilograms. As small as a rabbit; The smallest individual is as big as a big mouse. Although kangaroos are bigger than mice, they are less evolved than mice. Zoologists think kangaroos are lower mammals. Because the larvae of mammals generally develop in the placenta of their mothers, they are called placental mammals. Kangaroos, on the other hand, have no placenta. Their young are not only as thick as human fingers, but also very immature. Kangaroo cubs are discharged from their mother's reproductive tract and reach the root of their mother's tail, then waddle to their mother's breast-feeding bag along the wet path licked by their mother and suck the milk in the bag. After that, it will take several months for the cubs to complete most of their development. Zoologists believe that this way of raising children is far behind that of mammals with placenta. Because of this, kangaroos belong to marsupials in animal classification. On the other hand, rodents belong to mammals. So don't mistake a kangaroo for a mouse just by looking at the literal meaning. Let's talk about opossum again. In the United States, especially in South America, there are many small and medium-sized animals called opossums. These opossums are divided into several types: small opossums that live in trees and look like mice, fluffy opossums with thick fur all over their bodies, and webbed opossums suitable for aquatic life ... but almost all opossums have one thing in common, that is, they have sharp claws, long tails, are good at climbing, and can hang themselves upside down on branches and wind them with their tails. The characteristics of opossum parenting are similar to those of kangaroo. The newborn opossum is only the size of kidney beans. After the baby is born, the mother opossum puts it in the outer skin of the abdomen and feeds it for another two months. The name opossum comes from this. Because of this feature, animal taxonomists also classify them as marsupials. After living in the pouch of the mother mouse for two months, the young opossum can freely enter and leave the pouch, but will not leave the mother mouse. In another month or so, you can leave your mother and live independently. Opossum is used to hunting at night. They eat almost everything. It can be seen that the opossum we are talking about is also fundamentally different from the general rodent mammals, so it should not be attributed to mice.

Question 3: Are kangaroos rodents? Kangaroos, mammals, are distributed in Australia. There are 50 different types of kangaroos. The female kangaroo has a pouch in her abdomen. The fetus is not fully developed, so it needs to be fed in a warm pouch. Kangaroos are about 2 meters long and their tails are 1 meter long. It eats grass, shoots and leaves. A dozen kangaroos move in groups. The male kangaroo behaved like a man when he tried to win in the boxing match. Big grey kangaroo.

Question 4: Which country do Australian kangaroos come from?

Marsupials mainly live in Australia and its nearby islands, accounting for almost half of all mammal species in Australia. Among marsupials, kangaroos are the most famous and lovely rare animals, most of which are distributed in Australia, so Australia is called "kangaroo country".

Among them, the big red kangaroo has become a symbol of Australia, and even almost synonymous with Australia. Australia's national emblem is painted with a red kangaroo; There is also a red kangaroo running on the passenger plane of Australia international flight; In addition, the big red kangaroo is also widely used as a trademark pattern.

Marsupials are as backward as monotremes. Feeding offspring with a pouch looks decent, safe and comfortable. In fact, it is one of the slow-evolving animal species. Unlike Asia, Africa, America, Europe and other continents, Australia is home to many natural enemies of herbivores-large carnivores. If there were, the species and number of marsupials would not be today. When African lions pounce on herbivores such as zebras and giraffes, they often strike first. Because relatively speaking, parents run faster and older people have more escape experience. Children with marsupials are hidden in nursing bags. If there are enemies, cubs seem to be safer than marsupials, but this may be painful for the mother. How can she escape capture? Finally, both mother and son must die.

Fortunately, Australia is an island country, surrounded by water, isolated from other continents and inaccessible to herbivores, so it has become a paradise for kangaroos. Of course, some birds of prey (such as the wedge-tailed eagle) will also attack kangaroos, but they mainly prey on young kangaroos and kangaroos, and there is nothing they can do about adult kangaroos.

Although kangaroo doesn't look like a wild animal, it has a unique set of skills to resist enemies. When desperate, it will cross the rubicon and fight to the death: it quickly jumps into the tree, leans against the trunk and makes a scary sound. When the opponent gets closer, it will suddenly straighten its forelimbs, stab two dagger-like claws into the opponent's abdomen, grab the internal organs, or kick the opponent's abdomen with its hind legs and kick him to death. If the kangaroo is near the water, it will jump into waist-deep water, turn around and wait for the other person to swim, then grab the other person's head with its forelimbs and press it hard under the water. At this time, the other party had to struggle to escape to the shore, otherwise it would drown in the water.

In addition, the kangaroo's fast jump is also beneficial to avoid the enemy. Sometimes, it will wave its long tail at intruders. Therefore, hundreds of species of kangaroo family live safely in a paradise, and they have preserved this primitive animal attribute to this day.
