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.

Sporosarcina aquimarina is a Gram-positive, endospore-forming bacterium in the family Planococcaceae, isolated from marine coastal environments. It forms characteristic tetrad or sarcinal clusters of cocci and can produce heat-resistant endospores allowing survival under environmental stress. Members of Sporosarcina have attracted interest for their ability to induce calcium carbonate precipitation, with applications in biocementation.
