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.

Phaeographis dendritica is a corticolous crustose lichen forming pale to whitish patches on smooth bark with distinctive branched, dendritic lirellate apothecia. It inhabits humid, shaded temperate woodland, particularly old-growth forests in oceanic regions. Classified as Vulnerable, this species is threatened by habitat loss and the decline of ancient, undisturbed woodland ecosystems.
