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.

Tolypothrix rivularis is a filamentous, heterocyst-bearing cyanobacterium found in freshwater streams, rivers, and pools, often attached to rocks and aquatic plants in flowing water habitats. It can fix atmospheric nitrogen through heterocysts and forms false-branching filaments characteristic of the genus. This species contributes to nutrient cycling in lotic freshwater ecosystems across temperate zones.
