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.

Pelonema tenue is a slender, colorless filamentous bacterium in the order Achroonematales, found in the stratified, oxygen-depleted layers of freshwater lakes and brackish water bodies. It forms straight or slightly curved trichomes of narrow diameter in microaerobic to anaerobic zones. As a chemoheterotrophic organism, it participates in carbon cycling in hypolimnetic waters.
