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.

Russula sericatula is a brittlegill mushroom with a silky-textured cap in muted brown to olive-brown tones and white, brittle gills characteristic of the genus. It forms ectomycorrhizal associations with broadleaf and coniferous trees in temperate European forests. Listed as Data Deficient, its precise ecology, distribution, and population size remain poorly understood.
