koala

Iconic marsupial of eastern and southeastern Australia, koalas weigh up to 15 kg and spend up to 22 hours daily sleeping to conserve energy from their low-calorie eucalyptus leaf diet. Highly specialized to process toxic eucalyptus compounds that would kill most other mammals, they have gut microbiomes uniquely adapted for detoxification. Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.

red kangaroo

The largest kangaroo and largest marsupial on Earth, red kangaroos can stand 2 meters tall and weigh 90 kg, inhabiting the arid and semi-arid regions of inland Australia. Highly adapted to harsh desert conditions, they can survive without drinking water for long periods by extracting moisture from vegetation. Powerful hind legs enable 9-meter leaps and speeds up to 70 km/h. Males engage in ritualistic boxing contests to compete for females.
