Coco-grass

Coco grass (Cyperus rubicundus) is a perennial sedge in the family Cyperaceae, native to tropical and subtropical regions of Africa, South Asia, and Southeast Asia, but now naturalised as a weed across much of the pantropical zone, including the Americas, Australia, and the Pacific. The species forms dense tufts of grass-like foliage growing to 20–60 centimetres from creeping rhizomes and small, dark tubers in the soil. Flower heads are reddish-brown to purplish, borne on triangular stems in compact compound umbels. Like the closely related purple nutsedge (Cyperus rotundus) — one of the world's most problematic agricultural weeds — C. rubicundus spreads aggressively through both seed and vegetative means via its tuber-bearing rhizomes, enabling rapid colonisation of disturbed ground, irrigated fields, gardens, and roadsides in warm climates. The tubers serve as propagules that survive soil disturbance and are difficult to eradicate mechanically, making infestations persistent. Despite its weed status, the species has documented traditional uses: the dried rhizomes have been used medicinally in parts of Asia for gastrointestinal conditions and as an aromatic ingredient in perfumery and cosmetics. Cyperus rubicundus is classified as Least Concern by the IUCN, reflecting its wide distribution and robust, expanding populations in anthropogenic habitats globally. Research into biological control has targeted related invasive Cyperus species in some regions.

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.
