Alcanivorax venustensis is a marine gammaproteobacterium in the family Alcanivoraceae, specialized in degrading aliphatic hydrocarbons as a primary carbon and energy source. It is typically rare in unpolluted seawater but becomes highly enriched in oil-contaminated marine environments, playing a key role in natural bioremediation of petroleum spills. Like other Alcanivorax species, it has evolved extensive alkane hydroxylase systems for hydrocarbon degradation.

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.
