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.

Volvariella volvacea, the paddy straw mushroom, is a medium-sized mushroom with a distinctive volva at the base, grey-brown cap, and pink gills arising from free cultivation in tropical Asia for millennia. It grows on rice straw, compost, and decaying plant matter in tropical and subtropical regions of Southeast and East Asia. This saprotrophic fungus decomposes agricultural residues, particularly rice straw, and is widely cultivated as a food mushroom.
