Though often called koala bear but it is not a bear at all, the koala is a marsupial mammal. Koala is the representative of the phascolarctidae family.

The koalas are closely related to kangaroos and wombats; they are the epochal symbol of Australia.

Scientific Name of Koala:

The binomial name of koala bear is phascolarctos cinereus.

Information About Koalas:

The koalas can be found in the southern-eastern and eastern Australia, in the states of Queensland, Victoria, South Australia, and New South Wales. They prefer to live in the eucalyptus forests and spend much of their time on trees. Koala eats in the trees, sleep in the trees, and hang out in trees. They spend most of their time eating and sleeping. A fully grown koala is 2 to 3 feet tall, and the weight of a male koala is 50 percent more than females. The color of koala ranges from slate grey to reddish-brown, the fur of the koala is not soft but coarse. Koalas are big tree-hugging mammals with round, big ears, and a black oval nose. 

What is Koala’s Diet? (Koala Favorite Food)

Koalas are herbivorous who feed on eucalyptus; on average, a koala can eat 1 to 1.5 pounds each day. They usually bite during the night time and rest for 16 to 18 hours per day. The leaves of eucalyptus are fibrous and need time and energy to digest it, so the koalas sleep so much. Out of 700 species of eucalyptus, the koala can eat less than 50 species.

How Many Types of Koalas are there?

Koalas can be differentiated based on their color, size, and region. There are three types of koalas:

  1. Brown koalas
  2. Grey koalas
  3. Grey-brown koalas

Brown koalas- Brown koalas are the most common and most significant among all other koalas. These are known as Victorian or southern region koalas. The brown koalas have the thickest fur of all the Australian koalas. Male Victorian koala can stand 2 feet in height and can weigh 30 pounds, whereas females can weigh between 15 to 17 pounds. The thickest fur of these species helps them to survive in the cold climates of the southern Australian region.

Grey koalas- These are the second most common species of the koalas, which are found in Queensland. As the name suggested, the fur of these species is grey. Other names for grey koalas are Queensland koalas or the northern koalas. Among all the koalas, the coat of these species is the thinnest. Grey koalas are the smallest of all the other koalas; the male koala weighs 11 pounds and females weigh even less than the males. Grey koalas are the most threatened species across Australia. More than 80 percent of these species have lost their lives.

Grey-brown koalas- These species are native to the new south wales of Australia. Habitat loss is the biggest threat to the grey-brown species. Only 16,000 koalas of these species are left in the wild.

Baby Koala:

A koala baby is known as a joey; the female koala carries the baby for an evolution period of 35 days. The newborn joey is 2 centimeters long and weighs about 0.017 pounds. Soon the joey will climb in the mother’s pouch when it becomes too big for the bag, the joey will ride on its mother’s back. After one year, the joey is completely detached.

Facts about Koala:

  • Koalas have poor eyesight but have excellent hearing and other sense organs, which helps them to detect their prey.
  • Koalas are tree-dwelling mammals who have strong arms, sharp claws, and sturdy legs. They can move to a speed of 30 km per hour.
  • Koalas have two opposable thumbs on their fore paws, which allow them for a better grip.
  • It is believed that koalas didn’t need to drink water because they get sufficient moisture from the leaves of eucalyptus.
  • Koalas have healthy cartilage at the end of their curved spine.
  • Many koalas are subjected to the chlamydia bacterial infection, which is a stress-related disease, and this can weaken the immune system and can cause blindness.
  • Just like humans, koalas have fingerprints and they are the only mammal to have them.
  • Usually koalas don’t make noise, but the male has a loud call during the mating season.
  • Koalas have a scent gland on their chest, which they rub on the trees to mark their territory.
  • The average life span of a koala in the wild is between 10 and 14 years.

Koala Bear Extinct:

Koala bear is listed as ‘least concern’ under the International Union for Conservation of Nature (IUCN). Threats to the koala bear include habitat loss, deforestation, and death from traffic. Another threat to the koala is the chlamydia disease, which can lead to blindness, death, and infertility. In the year 2012, the Australian government declared koala bear as vulnerable. The estimated population of koalas is between 43,000 to 80,000, according to the Australian koala foundation.Koala bear is listed as ‘least concern’ under the International Union for Conservation of Nature (IUCN).
