climbing-oleander

Climbing Oleander, Strophanthus gratus, is a woody liana or climbing shrub in the family Apocynaceae native to tropical West and Central Africa, occurring in rainforest margins, gallery forest, and secondary forest from Senegal to Uganda. The species belongs to a genus celebrated for the cardiac glycosides and arrow poisons produced in the seeds; Strophanthus species were the source of the drug ouabain (g-strophanthin), historically used in cardiac medicine and by African hunters as an arrow poison applied to hunting darts. Climbing Oleander produces large, funnel-shaped flowers with white to pale pink twisted petals and a fringe of elongated lobes at the corolla mouth, borne in terminal cymes that are highly ornamental. The name 'climbing oleander' refers to the superficial resemblance of the flowers to the related Mediterranean oleander (Nerium oleander). The species climbs by twining its stems around supporting vegetation and is occasionally cultivated as an ornamental in tropical gardens. The seeds contain strophanthin and other potent glycosides that affect the cardiac system; all parts of the plant are toxic if ingested. The species is not currently assessed as threatened within its native tropical African 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.
