Schwarzköpfiger Haarstern

Geastrum melanocephalum is an earthstar fungus in the family Geastraceae, assessed as Endangered (EN). It produces distinctive star-shaped fruiting bodies with a dark-capped spore sac and is found in stable, undisturbed grassland and woodland edge habitats. Its endangered status reflects sensitivity to habitat disturbance and the decline of traditional land management practices.

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.
