Great White Pelican

One of the world's largest pelicans, great white pelicans have wingspans reaching 3.6 meters and inhabit shallow lakes and wetlands across Europe, Africa, and Asia. Social birds breeding in large colonies and foraging cooperatively — groups of pelicans corral fish into shallow water before scooping them in their expandable throat pouches. Their pouches can hold up to 13 liters of water. Listed as Least Concern globally 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.
