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.

Xylaria corniformis is a club-shaped, carbonaceous ascomycete fungus producing firm, horn-like or antler-shaped black stromata on decaying wood in tropical and subtropical forest habitats. It is a saprotrophic wood decomposer contributing to lignocellulose breakdown in forest ecosystems. Classified as Endangered, threats include tropical deforestation and the loss of old-growth forest habitats.
