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.

Planococcus citreus is a lemon-yellow pigmented, Gram-positive coccus distinguished by its motility via peritrichous flagella, an unusual trait among cocci. It inhabits marine coastal environments and is commonly found in seawater and marine sediments. This aerobic bacterium obtains nutrients by decomposing organic matter in saline environments.
