American Flamingo

The most vibrantly colored flamingo species, American flamingos display brilliant scarlet-pink plumage from the carotenoid pigments in their crustacean diet. Found in Caribbean coastal lagoons, salt pans, and mangrove swamps from the Bahamas and Florida through Central America and the Galapagos. Highly gregarious, they nest in huge colonies on mudflat mounds. Their distinctive deep pink color is used to signal health and reproductive quality to potential mates.

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.
