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.

Resupinatus poriaeformis is a small, grey to brownish, resupinate to dimidiate shell-like mushroom growing on decaying wood. It inhabits temperate and boreal forests, appearing on dead branches and woody debris of hardwoods. This saprotrophic fungus decomposes dead wood and contributes to nutrient cycling in forest ecosystems.
