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.

Listed as Endangered in 2022, with populations decimated by chlamydia disease, habitat clearing, and climate change.
