Common Raven

One of the most intelligent birds known, common ravens demonstrate problem-solving abilities rivaling great apes, including tool use, planning, and deceptive behavior. Found across the Northern Hemisphere from Arctic tundra to deserts, ravens are highly adaptable omnivores. They form complex social hierarchies, engage in cooperative foraging, and have been observed engaging in play. Their intelligence and black plumage have made them figures of mythology across many cultures.

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.
