Prachtkehlelfe

A tiny, high-altitude Andean woodstar hummingbird, male gorgeted woodstars have a spectacular iridescent pink-purple gorget that is disproportionately large relative to their 2.5 g body. Found in montane forest edges and gardens from Colombia and Venezuela to northwestern Peru at elevations of 1,500–3,500 meters. Like all woodstars, they perform buzzy, insect-like hovering flight in open areas near flowers. They enter deep nocturnal torpor — a near-death metabolic state — to survive cold Andean nights.

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.
