Fascinating Facts About Koalas

Koalas, the cuddly marsupials, have captured the hearts of many worldwide. Their iconic image is often associated with Koala-shaped cookies, especially popular in Vietnam.

Koalas, found along the eastern and southern coasts of the main island, typically measure between 60-85cm in length and weigh 4-15kg. Their fur ranges from silver-gray to chocolate brown. Northern koalas are smaller and lighter in color compared to their southern counterparts.

Koalas primarily feed on eucalyptus leaves, which are low in nutrients and difficult to digest. Researchers have found that Koalas need to consume 2000 eucalyptus leaves in one meal to sustain their bodily functions. With such a meal, it takes them approximately 100 to 200 hours to digest. Consequently, they opt for sleep to conserve energy.

Koalas possess specialized genes in their organs, particularly the heart and liver, aiding in the identification of the components of leaves and juices, enabling them to detect sweetness. Additionally, they have a heightened sense of taste, especially for bitterness, surpassing that of other animals. Various receptors in their bodies allow Koalas to assess the nutritional value of plants. Despite the significant presence of hydrocyanic acid, a lethal substance in eucalyptus leaves, Koalas are relatively unaffected by its toxicity. They rarely drink water to avoid attacks from other animals, except in cases of drought or forest fires. Their consumption of eucalyptus leaves contributes significantly to the ecosystem by pruning the trees, promoting better air circulation in the forest, and allowing low-lying plant species to receive sunlight.

Koalas can produce at least 4 distinct vocalizations for communication, which are far from endearing despite their outward appearance. These include grunts, growls, cries, and sounds that attract female Koalas during mating season. These sounds travel through the forest and can be detected from a distance of about 1 km. Upon hearing these sounds, females discern the location and size of the males, as they typically prefer larger males.

According to scientific literature, Koalas have poor eyesight and rely heavily on other senses. With excellent hearing and keen sense of smell, they can detect conspecifics as well as other carnivorous species or locate favorite foods. Their fur color ranges from silver-gray to chocolate brown. Generally, Koalas in northern populations are smaller and lighter in color compared to those in the south.

The koala bear, one of Australia's iconic creatures, has been declared 'functionally extinct.' In case you're unfamiliar, functional extinction of a species or a group of species falls into one of three scenarios:

• No fossils remain, no evidence of their existence.
• Decreasing population no longer plays a significant role in the ecosystem.
• Population of the species is critically low, insufficient for reproduction.

Deforestation, climate change, and increased warmth, coupled with droughts, have led to dwindling food resources. The dwindling koala population signals another event, evidence of an impending sixth mass extinction event on our planet.

A newly released report by the United Nations suggests that 1 million species could disappear soon, with many species going extinct within decades, all due to human impact.

Continuing on the subject of this article, currently, 80% of the koala's natural habitat has vanished. According to AKF, koalas are threatened by wild dogs and vehicular traffic; both factors are responsible for killing up to 4,000 koalas annually.

The Australian Koala Foundation leads the charge in koala conservation efforts. They have been pressing the government to protect this adorable animal. The organization has also been pushing local authorities to support them in various strategies concerning education, enacting laws to safeguard koalas, monitoring this animal species, and many other actions.

Despite being an animal species exclusive to Australia, the country has several non-profit organizations aimed at launching campaigns worldwide. If you wish to contribute, you can donate directly, purchase charitable products, and even plant a eucalyptus tree. But perhaps the most exciting part of the program that might melt your heart is that you can foster a koala bear.

Koalas are among the most unique creatures of Australia's biodiversity. With ongoing efforts, there's hope to prevent it from becoming a species beyond our saving from extinction.
