From the time early settlers from Europe first laid eyes on koalas in Australia, they didn’t understand what kind of animal it was. Some thought these were monkeys because koalas can climb trees, others guessed it was a type of small bear, but they were wrong. Koalas are actually related to the kangaroo and wombat, and even though many people refer to them as “koala bears”, they are actually marsupials.
Female marsupials have pouches that are meant to hold their young, and the pouch functions as a safe place until they fully develop. However, unlike kangaroos, koala pouches are located lower on the stomach and require the mother to use her sphincter muscle to keep the pouch closed, so that the little joey (baby koala) doesn’t fall out. Pregnancy lasts up to 35 days, and once born, a baby koala will instinctively crawl from the birth canal towards the pouch where it will reside as it grows, just like a kangaroo joey.
Koalas are not big animals, although southern koalas are larger than northern koalas, and can reach 85 cm in length and weigh as much as 13 kg.
By their very nature, koalas like to climb, and they live a comfortable tree-dwelling life. Thick fur and tough skin allow koalas to perch snugly between branches for many hours. Their strong forepaws are ideal for gripping tree branches, which allows them to climb high enough to reach eucalyptus leaves for nourishment. Interestingly, although there are hundreds of types of eucalyptus trees, koalas are finicky eaters and will seek out trees with the best-tasting leaves.
The digestive system of these animals effectively breaks down the fibre in eucalyptus leaves, and even the toxins in eucalyptus that are poisonous to other animals. Because of their low-calorie diet and slow-moving nature, koalas need a lot of sleep, approximately 20 hours per day.
Koalas are a native species of Australia, and they depend on native plants such as eucalyptus trees to survive. That is why protecting natural eucalyptus forests is important, for the sake of koalas and other animals that depend on them.
Many of Australia’s native animals suffer from large land development projects, and without any effort to bring public awareness to animals such as the koala, many of Australia’s native animals are in danger of being lost.
Black Snake Productions is a wildlife conservation group that promotes awareness of Australia’s native animals by offering interactive education programs for children and adults. You can discover Australia’s unique animals with a hands-on wildlife incursion for your school or kinder. See birds, reptiles and other native animals, and learn how you too can promote wildlife conservation at your school or in your neighbourhood.
