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.

Red-crowned Crane

One of the rarest cranes in the world, red-crowned cranes stand 1.5 meters tall and are revered in East Asian cultures as symbols of longevity, fidelity, and good fortune. They inhabit wetlands and marshes of Russia, China, Korea, and Japan, performing elaborate and graceful courtship dances involving synchronized leaps, bowing, and calls. Endangered, with the wild population estimated at just 2,750 individuals, threatened by wetland drainage and habitat loss.
