Amerikanische Königslibelle

<em>Anax junius</em>, commonly known as the common green darner, is a large dragonfly belonging to the genus Anax within the family Aeshnidae. This species occupies virtually all terrestrial and freshwater habitats, and its range is centered on the United States, where it is one of the most recognizable and widespread dragonfly species. Common green darner is assessed as Least Concern on the IUCN Red List. The species is well known for undertaking long-distance migrations, with populations moving southward in autumn and northward in spring across North America. Adults are typically found near ponds, lakes, and slow-moving streams where females deposit eggs in aquatic vegetation. Biological traits of this species remain poorly documented in the scientific literature.

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.
