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.

Leptolyngbya perelegans is a thin-filamentous cyanobacterium in the family Leptolyngbyaceae, found in diverse environments including soil crusts, freshwater biofilms, and marine intertidal zones. Its narrow trichomes are enclosed in a thin, often indistinct sheath and glide slowly across substrates. The genus Leptolyngbya is morphologically diverse and has undergone substantial taxonomic revision with molecular phylogenetics.
