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.

Mute Swan

The most commonly encountered swan globally and one of the largest flying birds, mute swans weigh up to 15 kg and inhabit lakes, rivers, and coastal bays across Europe and Asia, with widespread introduced populations in North America and Australia. Despite their name, mute swans produce a range of hissing, grunting, and wing-whistling sounds. Males aggressively defend territories and are capable of injuring humans and drowning dogs with powerful wing strikes.
