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.

Sparkling Violetear

A large, brilliant hummingbird of the Andes and high Venezuelan tepuis, sparkling violetears display glittering blue-green plumage with an iridescent violet-blue ear patch and chin that sparkle intensely in sunlight — delivering on their evocative name. Found at elevations of 1,200–3,000 meters across Venezuela, Colombia, Ecuador, and Peru in montane forest and scrub. Among the most common Andean hummingbirds, they are highly aggressive and vocal territory defenders at flower patches.
