Unveiling the Secrets of Koalas: IELTS Reading Passage With Questions & Answers

Short Intro:

Koalas are one of Australia's most iconic and beloved marsupials, known for their tree-hugging habits and sleepy demeanor. Understanding these creatures is not only fascinating for wildlife enthusiasts but also serves as an excellent topic for IELTS reading test preparation. The following passage delves into the intriguing life of koalas, providing valuable information designed to test your reading comprehension skills.

Passage:

The koala, a symbol of Australia's unique wildlife, leads a mostly solitary life in the eucalyptus forests. Often mistaken for a bear, the koala is actually a marsupial, a special class of mammals often characterized by a pouch where they carry their young. These creatures spend up to 20 hours a day in slumber, nestled in the nooks of trees, conserving energy for their predominantly nocturnal activities.

Koalas are herbivorous, with a diet that consists almost exclusively of eucalyptus leaves, which are tough, fibrous, and generally low in nutrition. Remarkably, koalas have a highly specialized digestive system with a long caecum that allows them to detoxify the poisonous compounds found in eucalyptus leaves while extracting the essential nutrients.

Despite their peaceful demeanor, koalas communicate with a range of vocalizations, from snores to bellows, especially during the mating season. Each koala's home range is scent-marked and dotted with 'scent trees,' which are central to their territorial behavior.

With their thick, woolly fur that acts as an insulator against both heat and cold, koalas are well-adapted to their environment. However, they face threats from habitat destruction, disease, and climate change, which continue to challenge their survival.
