Description of Koala

koala (Phascolarctos cinereus), also called koala bear, arboreal marsupial on the east and south coast of Australia, which belongs to the Phascolarctidae family (suborder of Vombatiformes).

The koala is between 60 and 85 cm (24 to 33 inches) long and weighs up to 14 kg (31 LB) in the southern part of its range (Victoria and South Australia), but only about half of subtropical Queensland in the north. Practically without a tail, the body is robust and gray, with a light yellow or cream breast and spots on the croup. The broad face has a wide, rounded, leathery nose, small yellow eyes and large fluffy ears. 

The feet are strong and claw-like; the two inner digits of the front feet and the innermost digit of the hind feet are facing the handle. They also have one of the smallest brain-body-weight ratios of all mammals and are not considered very intelligent creatures.  Due to the superficial similarity of the animal with a small bear, the koala is sometimes, albeit mistakenly, called a koala bear.

Have you ever heard someone call a koala a "koala bear"?"Well, just like bears, koalas are mammals, and they have round, fuzzy ears and look cute and cuddly, like a teddy bear. But koalas are not bears. They belong to a group of marine mammals called marsupials. Marsupials include Kangaroos, wallaroos, wallabies, wombats, possums, and opossums. Koalas look soft, but their skin resembles the thick wool of a sheep. They also look cute, but koalas are not domesticated and do not make good pets.

Koalas are best known for their rounded body image and distinctive ears and noses. Like other marsupials, females have a permanent pouch to raise their young. Koala bags are placed on the lower body of a koala. The pockets open outwards so that a misoe (baby) can ascend the birth canal. If a misoe and miso are present, your mother will use her sphincters to make sure that the bag is closed so that your baby does not fall down.

Koalas are particularly well suited to live their lives in trees. Their paws help them grab trees and deftly climb them. The pads on the paws are very rough and help with their grip. Each leg has five digits. The front legs have two digits opposite the remaining three digits. This helps with grip strength when climbing. Its fur, usually light gray or brown, is very thick and protects it from low and high temperatures.

Distribution of Koala

Koalas are common in eastern and south-eastern Australia, including north-eastern, central, and south-eastern Queensland, eastern New South Wales, Victoria, and parts of south-eastern South Australia. They are found in habitats ranging from relatively open forests to forested areas, and in climates ranging from tropical to cold temperate climates. In semi-arid climates, koalas prefer riparian habitats, where nearby streams and streams provide shelter during periods of drought and extreme heat.

Species of Koala

There is a kind of koala, but scientists disagree on whether there is a subspecies or not. The three most common subspecies of koalas are considered: Phascolarctos cinereus adustus (North/Queensland), Phascolarctos cinereus cinereus (New South Wales) and Phascolarctos cinereus victor (Victorian). These subspecies are classified according to slightly different physical characteristics, such as physical size and skin characteristics. Due to these features, some scientists believe that there are three subspecies, two more and none.

The cry of the koala

Koalas make different types of sounds depending on the situation. When stressed, they make cries similar to those of a human baby. During the breeding season, males can be heard growling loudly to attract females and intimidate other males. Women and their boys, on the other hand, lovingly exchange screams and snapshots.

Habitat of Koala

Koalas are native to the southeast and east of Australia and live in Eucalyptus forests. They need a lot of sleep to give them time to digest their food. Always being on the ground would be a disadvantage, since predators could easily catch them. Instead, they adapted to life in Eucalyptus trees, with the back firmly planted in the branch fork so that they could chew the leaves and doze off as much as they wanted without feeling threatened.

Eucalyptus forests protect and feed koalas. Koalas are adapted to live in the bends of the branches: they have a reduced tail, a curved spine, and a rounded back. But they, if necessary, move to the ground to get from tree to tree or to a new area. In hot weather, koalas select the coolest trees and coolest places of these trees (against the trunk and other low, shady branches) for rest. On colder days, koalas tend to rest further away from the trunk, where they can absorb the sun's heat.

The hands and feet of koalas are adapted in such a way that they cuddle and hold on to branches very effectively. Their hands have two opposite thumbs to increase the grip (they have only one), and sharp claws to dig out the bark. The feet have a toe, which actually consists of two fused toes, with which they fix themselves, and a toe that does not have a claw, which serves as a thumb for grasping. Rough, ribbed pads on the hands and feet help to grip them and give them traction. Strong arm and shoulder muscles help a koala climb 150 feet (46 meters) to the top of a tree and jump between branches.

Diet of Koala

By their nature, koalas are loners. They are most active at night and spend most of their time sleeping and eating. Koalas eat only eucalyptus leaves. Eating leaves from one type of plant may seem boring, but there are more than 600 different types of Eucalyptus, and from the point of view of a koala, everyone looks and tastes very different! Koalas prefer leaves of about three dozen varieties.

Like many plants, Eucalyptus trees produce some toxic compounds as adaptations to avoid being eaten. Most herbivores do not tolerate eucalyptus trees because of these compounds, but koalas specialize in this area! They are co-adapted to be able to absorb these toxins at least in some species of eucalyptus. But koalas seem to know their limits. Conservation scientists have observed that koalas avoid certain plants seasonally. Plant analyses revealed higher-than-usual concentrations of certain toxins.

Koalas grind hard Eucalyptus leaves with cheek teeth. it does not consume a lot of calories from its diet, but it saves energy by moving from time to time and sleeping up to 20 hours a day.

At the San Diego zoo, koalas receive fresh branches of various species of Eucalyptus every day. These picky eaters can choose their favorite varieties. Our koalas eat 1 to 1.5 pounds (454 to 680 grams) of leaves daily.

Reproduction of Koala

Koalas usually breed from August to February. Male koalas attract females with their powerful vocal cords. Females usually have one koala per year and produce about six pups over the course of their lives, as females do not always breed every year.

After pregnancy, a koala will give birth after a gestation period of just over a month (about 35 days). The child is called "Joey" and is usually very small. The child can weigh under it 0.0025 Pounds and measure less than an inch long, the size of an almond. He is blind from birth and has no hair. It moves from the birth canal to the mother's pouch, where it will remain for the first six to seven months of life. Even after developing to the point where it is no longer in the mother's pocket, the sound Joey often stays with the mother until her next brother or sister appears from the mother's pocket the next year.

The koala is the only member of the family Phascolarctidae. Unlike other arboreal marsupial tree pouches, the bag opens to the back. Births are unique and occur after pregnancy from 34 to 36 days. At the age of five months, the young male (with the names Joey) first takes his head out of his pocket. After weaning, Joey comes out of the bag completely and clings to her mother's back until she is almost a year old. A koala can live about 15 years in the wild, a little longer in captivity.

Behavior of Koala

Marsupial females have a bag in which they carry their baby, called a pouch. Many marsupials, such as kangaroos, have a pouch that opens upwards towards the head. But koalas have a pouch that opens towards the hind legs. This adaptation prevents burrowing marsupials, such as wombats, close relatives of koalas, from getting dirty while digging in their pockets. Although prehistoric koalas have finally stopped digging and living in trees, they still have a primitive back pocket.

A koala, like other marsupials, begins its life in a very unusual way. At birth, it has only the size of a large jujube and is not yet fully developed. Indeed, a newborn Joey can not see or hear, but it can certainly soar! Shortly after the birth of Joey uses his front legs and strong hands to crawl from the birth canal to his mother's pocket. Joey clings to one of her two nipples in this warm, safe place where she drinks milk and grows for the next six months.

Even after he starts to get out of the bag, Joey returns when he wants to hide or sleep. Sometimes he walks on his mother's stomach. After growing out of the bag, Joey climbs on his mother's back and holds her with strong hands and feet. After about a year, he can only live in trees.

Koala joey learns to eat eucalyptus leaves little by little. In the beginning, Joey attacks the leaves with his mouth. Your first attempts look like a moving apple game where the nose is in the way and pushes the leaves out of reach! Fortunately, Joey keeps trying until it succeeds. After all, they understand how to grab the leaves with their hands and take them in their mouths.

Animal care experts at the zoo say that each koala has a unique personality. Koalas make various vocalizations, from snoring to bellowing and screaming. Our conservation scientists are trying to understand why male koalas are threatened. Is it to tell other men to stay away, or to invite women to visit them? The bellows sound like a mix of a speeding bike and a sniffing pig!

The male koala has a bare spot on the chest, where his olfactory gland is located. The male rubs this place against the trunk or branch of a tree to mark it with his peculiar smell. We found more than 35 chemicals that make up the fragrance. We took samples from males at different times of the year to see if the smells changed and found that male koalas smelled more in the spring when they were trying to attract a mate.

Threats of Koala

Koalas have few natural predators, although sometimes a dingo or a large owl can catch them. The most common direct of death of koalas are caused by motor, vehicles, and dogs. Koalas are certainly safer in the trees.

He was once hunted extensively for his fur. Protected today, it is threatened by the degradation of its biotope, which is completely dependent on the eucalyptus forests, of which it feeds exclusively on the leaves. It pays a high price for the forest fires that are multiplying on the island continent, although Australians are very determined to save this animal, which is part of their national treasures. The wild population is estimated by the International Union for Conservation of Nature at just over 300,000 individuals.

Koalas are mainly threatened by the loss of their habitat. The intrusion of humans into their habitat through deforestation has a major impact on their survival. They can also be affected by forest fires and diseases. Koalas are susceptible to bacteria that cause chlamydia. This disease can lead to the development of conjunctivitis-an eye infection that can lead to blindness. Chlamydia can also lead to pneumonia and infections of the urinary tract and reproductive system. The incidence of complications due to chlamydia is increasing in koala populations suffering from high environmental stress.

Koalas and humans interaction

Humans and koalas have a long and diverse history. In the early 1900s, more than a million people were killed for their furs. The koala population risked being wiped out before the practice ended. Koalas can be very aggressive when disturbed or surprised by humans in their natural habitat. They defend themselves with sharp teeth and sharp claws that look like claws. These structures can destroy the skin and cause significant damage.

Number of inhabitants of Koala

The estimated population of koalas in the wild is about 300,000 mature individuals throughout Australia. On the IUCN Red List, the koala is classified as endangered (Vu) with a tendency to decline in population.

LifeSpan of Koala

The koala can live from 13 to 20 years, and females have a longer life expectancy than males.

10 Amazing facts about koalas

1- Koalas are found in the eucalyptus forests of eastern Australia. They have gray fur with a cream chest and powerful clawed feet, perfect for life on branches!

2- Cuddly critters and koalas are about 60-85 cm long and weigh about 14 kg.

3- Although you may have heard people call them koalas "bears", these amazing animals are not bears, but marsupials. Most marsupials are a group of mammals and have pockets in which their newborns develop.

4- When a small koala is born, called Joey, it immediately climbs into his mother's bag. Blind and earless, Joey uses his keen sense of touch and smell as well as his natural instinct to find his way.

5- A Joey grows and develops in the stock market for about six months. As soon as the young male is strong enough, he climbs on his mother's back for another six months, using only the bag for food.

6- Koalas grow and become large eaters, passing up to a kilogram of eucalyptus leaves in a day! They are also picky, choosing the most nutritious and tasty leaves from the trees in which they live.

7- These magnificent mammals take their name from an Aboriginal term meaning "without drinking". It is believed that this is due to the fact that koalas get almost all their moisture from the leaves that they eat, and rarely drink water.

8- Eucalyptus leaves are super tough and poisonous! Fortunately for koalas, they have a long digestive organ called the cecum, which allows them to break up leaves unscathed.

9- Just like our furry friends! Koalas do not have much energy and if they do not delight in the leaves, they spend their time sleeping on the branches. Believe it or not, you can sleep up to 18 hours a day!

10- Although these beautiful creatures are protected by law and are not classified as endangered species, their habitat is threatened. Unfortunately, about 80% of the habitat of koalas was lost due to human habitation, drought, and forest fires.
