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.

Orange-cheeked Waxbill

A charming small estrildid finch with an unmistakable orange cheek patch set against a grey head, brown back, and pale white underparts, orange-cheeked waxbills are native to the humid forests and forest edges of West and Central Africa. They feed on small grass and weed seeds, often near water. Widely kept as aviary birds, they have established feral populations in parts of Puerto Rico, Europe, and Asia. Active and social, they pair bond strongly.
