Kangaroos are herbivores, eating all kinds of plants, and some also eat fungi. Most of them are active at night, but some of them are active in the early morning or evening. Different kinds of kangaroos live in different natural environments. For example, Porto-Lloyd kangaroos build their own nests, while tree kangaroos live in bushes. Large kangaroos like to use trees, caves and rock cracks as shelters. kangaroo
All kangaroos, no matter how big they are, have one thing in common: the hind legs with long feet are strong and powerful. Kangaroos jump instead of running. They can jump up to 4 meters and as far as 13 meters, which can be said to be the tallest and farthest mammals. Most kangaroos live on the ground, and it is easy to distinguish them from other animals when they jump from their strong hind legs. Kangaroos keep their balance with their tails when jumping. When they walk slowly, their tails can be used as the fifth leg. Kangaroo's tail is thick and long, full of muscles. It can not only support the kangaroo's body when it is resting, but also help the kangaroo jump faster and farther when it jumps. All female kangaroos have a pouch with four nipples in it. "Cubs" or kangaroos are kept in nursery bags until they can survive in the outside world. Kangaroos belong to Kangaroo family, which refers to Kangaroo suborder, Kangaroo order, marsupials, mammals, Chordata and animal kingdom. They are famous mammals in Australia and occupy a very important ecological position in Australia. Kangaroos have short forelimbs and developed hind limbs. They often lift their forelimbs and jump on the ground with their hind legs instead of running. Kangaroos are generally taller, and there are kangaroos.
2.6 meters, weighing about 80 kilograms. Kangaroos are often used as national symbols of Australia, such as the green triangle kangaroo, to represent Australia's manufacturing industry. Kangaroos often appear in expressway, which means kangaroos often appear nearby, especially when driving at night. Kangaroos have poor eyesight, are curious about the light, and will jump over to "see". However, because of the high reproduction rate of kangaroos, even if they are accidentally killed, they are not responsible. There will be a special person to take away the kangaroo's body. Kangaroos usually live in groups, sometimes as many as hundreds. But some smaller kangaroos, such as wallabies, live alone. Kangaroos can't walk, they can only jump, or run and jump with the help of their front legs and hind legs. Kangaroos are nocturnal animals. They usually come out for food a few hours after sunset and return to their nests shortly after sunrise. Kangaroos generally live in the wild, or they may be raised by people. When driving on the road, wild kangaroos will suddenly rush out. Australian drivers should be careful.
Edit the section on growth and reproduction.
Kangaroos breed once or twice a year. Kangaroos are born about 30-40 days after fertilization. They are very tiny, have no vision and little hair, and are stored in their mother's pouch immediately after birth. It was not until 6-7 months ago that I began to leave the pouch for a short time to study life. I can't be weaned and leave the nursing bag until one year later, but I still live near the kangaroo mother and get help and protection at any time. Kangaroo mothers can have kangaroos at the same time.
A kangaroo is outside the bag, a kangaroo is inside the bag and a kangaroo is going to be born. When kangaroos grow up to four months, all their hair grows together. Their backs are dark gray and their bellies are light gray, which looks good. At the age of five months, sometimes, the kangaroo sticks its head out and the mother kangaroo will press it down. Kangaroos are becoming more and more naughty. When its head is pressed, it will put its legs out again, and sometimes it will drag its small tail out of the pocket. Sometimes, such a big kangaroo will shit and pee in the pouch, so mother kangaroo has to "clean" the pouch frequently: she opens the pouch with her front legs and licks the inside and outside of the pouch carefully with her tongue. After staying in the pouch for seven months, the kangaroo began to jump out of the pouch and move outward. But once frightened, it will soon return to the pouch. At this time, the nursing bag has also become like a rubber bag, which is very elastic and can be opened and closed to facilitate kangaroo access. Finally, the kangaroo grew into a baby bag, which could no longer be held, so it had to be moved out of the bag. But it still has to live on its mother's milk, so it sticks its head into the pouch to feed. After three or four years, kangaroos can mature and become big kangaroos with a height of 1.6m and a weight of 100kg. At this time, its physical strength has reached its peak and it can jump 65 kilometers per hour; A sweep of the tail can kill people. As for the female kangaroo, because it has two wombs, the cub in the right uterus has just been born, and the embryo in the left uterus is pregnant with the cub. After the kangaroo grows up and leaves the pouch completely, the embryo begins to develop. Wait about 40 days before being born in the same way. This way, the left and right uterus take turns to get pregnant. If the external conditions are right, mother kangaroo will have to be busy with her children.
Edit the living habits of this paragraph.
Kangaroos feed on short, moist grass close to the ground, leaving long grass and hay to other animals. Individual species of kangaroos also eat leaves or small tree teeth. Miocene carnivorous kangaroo
The "racial discrimination" of kangaroo family is very serious. They can't tolerate foreign members entering the family, and even don't welcome family members who have been away for a long time. Even if the family accepts a new member, it must be taught a lesson. After new members learn many "rules", they can be integrated with their families.
Edit this paragraph of Australian kangaroo
Kangaroos belong to marsupials. The marsupial is a primitive mammal. At present, there are only 150 species in the world, which are distributed in grasslands and jungles in Australia, North and South America. Red kangaroo is the most famous marsupial. kangaroo
Kangaroos only live in Australia and are regarded as the symbol of their country by the Australian people. There is an image of a kangaroo on the national emblem of Australia. Red kangaroo and kangaroo in our zoo are "distinguished guests" directly from Australia. Before Europeans entered the Australian continent, kangaroos' footprints were almost all over the Australian continent. However, by forty or fifty years ago, the number of wild kangaroos in Australia had drastically decreased. Many people even worry that this precious animal will become extinct and call on people to protect them. Since then, the number of kangaroos has gradually increased due to proper protection. It is estimated that there are120,000 kangaroos of all kinds in Australia, which is an amazing number.
Edit the characteristics of kangaroos in this paragraph.
In the wild, kangaroos mainly eat all kinds of weeds and shrubs; When they arrived at the zoo, they were fed hay and carrot kangaroos.
Cloth, vegetables, apples, biscuits, and black beans are very particular about eating because of their many kinds of food and rich nutrition. A strange thing happened in Chicago Zoo, USA: there were 52 kangaroos there, and 49 of them died suddenly within one year! They quickly invited experts to "consult". Zoologists have studied kangaroo feed and found that this feed lacks calcium and some minerals, which are necessary for kangaroo life. Therefore, they added alfalfa, oats and various mineral-rich vegetables to kangaroos. Within a month, the remaining three kangaroos all recovered. Kangaroos have short forelimbs, and their forepaws can catch things. The hind limbs are long and stout, and their jumping ability is particularly strong. When being chased by the enemy, you can jump seven or eight meters away, two meters high. In a zoo in Europe, once a kangaroo suddenly jumped up, jumped over a wall more than two meters high, jumped to the hippopotamus pond next door, and scratched the hippopotamus's nose with its front paws, scaring the hippopotamus to a loss. In the wild, when kangaroos are chased by the enemy, they have their own unique counterattack methods. With their backs to the trees, they hit the ground with their tails and kicked the running enemy's abdomen with their powerful hind legs. However, kangaroos are relatively docile and honest animals in zoos. They are carefully taken care of, eat nutritious feed and get used to life in the zoo. In cold weather, I moved into a greenhouse with big glass windows to live.
Edit this paragraph and get in touch with kangaroos.
One year, a big gray kangaroo here was pregnant. Breeding in the zoo is rare! I take care of the pregnant kangaroo, send it nutritious food every day, and carefully observe its every move. The female kangaroo is pregnant for about 40 days and gives birth. It gives birth in a very special way: the immature baby kangaroo crawled out of its mother's cloaca. Kangaroos are only 2 cm long and weigh less than one gram, which is not as thick as my little finger. Its eyes and ears are closed, and its hind limbs are wrapped in a layer of fetal membrane. The whole body is fleshy red and wriggles like an earthworm. kangaroo
At this time, the female kangaroo was lying on her back, her tail sticking out between her legs and lying quietly. It licked a wet "road" from the root of its tail to the pouch with its tongue. Although the kangaroo is deaf and blind, it instinctively swings from side to side along the "path" licked by its mother with its powerful forelimbs, and climbs hard. After a long climb, I finally climbed into the pouch. As soon as he climbed into the pouch, he began to look for nipples. There are four nipples in the pouch. The kangaroo groped for a long time and finally held a nipple. As long as you hold it, the nipple will swell up quickly and fill the kangaroo's mouth. It will hang on the nipple for several months and continue to develop in the mother's pouch. Kangaroos don't suck milk, but rely on the automatic contraction of their mother's nipples to spray milk into their mouths. Kangaroos don't excrete, they just eat and don't pull. When this little kangaroo lived in the pouch for more than two months, something unexpected happened. That day, I went to the kangaroo room early in the morning to check on the kangaroo mother and child. When I stepped into the door, I found the baby kangaroo lying on the ground, while the mother kangaroo just squatted and watched. Apparently, the mother kangaroo was frightened at night and put the baby kangaroo in the pouch.
After being thrown out, the kangaroo can't climb back, and the kangaroo mother can't pick it up and put it back in the bag. I quickly opened the door and went in, picking up the kangaroo. I feel cold when I touch it. I was shocked and ran to the boiler room in my arms. I put the kangaroo in my clothes and squatted by the boiler, hoping it would recover? I put it back next to mother kangaroo, stroking mother kangaroo's pouch with my hand, and carefully put the baby kangaroo back into the pouch. Although I know it's dangerous, kangaroos have strong hind legs. It is said that in Australia, someone was kicked off his head and thigh by a kangaroo. However, in order to save the kangaroo's life, I also can not consider a lot. Finally, all went well, and the kangaroo was put back into the pouch and saved. If such a thing happens in the wild, kangaroos will die.
