Chaetoceros minimus is a tiny marine planktonic diatom in the family Chaetocerotaceae, distinguished by elongate setae projecting from the corners of each cell. It is among the smallest species in its genus and is widespread in coastal and open ocean waters where it contributes significantly to marine primary production. Like other chaetoceroids, it can form chain colonies and plays an important role in carbon export to the ocean floor.

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.
