Greater Flamingo

The most widespread flamingo species, greater flamingos reach 1.2 meters in height and inhabit saline and alkaline lakes across Europe, Africa, and South Asia. Their distinctive pink coloration derives from carotenoid pigments in the algae and crustaceans they filter-feed through specialized bent bills. They breed in dense colonies numbering tens of thousands on hypersaline lakes toxic to most other species. Listed as Least Concern with stable populations.

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.
