Range

Found in Australia. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

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.

Methanococcus voltae is a mesophilic methanogenic archaeon in the family Methanococcaceae, notable for being one of the first methanogens for which genetic transformation was developed. It inhabits marine sediments and produces methane by reducing carbon dioxide with hydrogen as the electron donor. Its model organism status has made it instrumental in unraveling fundamental aspects of archaeal cell biology and genetics.
