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.

Viridian Metaltail

A medium-sized hummingbird of the high Andes of Colombia and Ecuador, viridian metaltails inhabit open páramo grasslands and forest edges at 2,900–4,600 meters elevation. Males display distinctive green plumage with a glittering teal-green tail, while females are duller green below. Like all hummingbirds, they feed on nectar and small insects, hovering in stationary flight with wingbeats exceeding 50 per second. Listed as Least Concern with stable Andean populations.
