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.

Ochrolechia pallescens is a crustose lichen in the family Ochrolechiaceae, assessed as Endangered (EN).

Its endangered status reflects severe decline due to loss of old-growth and veteran trees across its range.
