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.

Rock Pigeon

Among the world's most successful birds, rock pigeons are native to sea cliffs and caves of Europe, North Africa, and South Asia but have been domesticated for thousands of years and introduced globally to every urban center on Earth. Their exceptional homing ability — navigating thousands of kilometers using magnetic fields, sun position, and landmarks — has made them vital military messengers and racing sport birds. Today, feral populations inhabit every major city worldwide.
