Chrustusdorn

The Christ plant (Euphorbia milii) is a woody succulent shrub in the family Euphorbiaceae, native to Madagascar. It is one of the most popular ornamental succulents globally, widely cultivated for its bright floral bracts — actually modified leaves surrounding small, inconspicuous true flowers — which appear in red, pink, yellow, or white in wild and cultivated forms. The stems are densely covered with stout spines, contributing to another common name, crown of thorns, derived from the legend that Jesus's crown of thorns was made from this species, though the plant is native to Madagascar and this association is symbolic rather than historical. Euphorbia milii is extremely drought-tolerant and thrives in warm, dry conditions with minimal watering, making it well suited to indoor cultivation and tropical to subtropical outdoor gardens. Like all Euphorbia species, it produces a milky latex sap that is irritating to skin and toxic if ingested, requiring careful handling. The species is a member of one of the largest and most diverse plant genera, Euphorbia, which spans succulents, shrubs, and trees across multiple continents. In Madagascar, wild populations are affected by ongoing deforestation, though the species is widespread in cultivation globally.

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.
