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.

Purple-backed Thornbill

A tiny, jewel-like high-Andean hummingbird, male purple-backed thornbills display glittering violet-purple back and rump feathers with a distinctively short bill adapted for short-tubed flowers. Found in open páramo grasslands and cloud forest edges at elevations of 2,500–4,500 meters in Venezuela, Colombia, Ecuador, and Peru. Despite their small size, they are aggressive territory defenders at flower patches. Their tiny size and high-altitude specialization make them one of the most cold-adapted hummingbirds.
