Common Stinkhorn

<em>Phallus impudicus</em>, commonly known as the common stinkhorn, is a basidiomycete fungus belonging to the family Phallaceae within the order Phallales. It is widely distributed across Europe and North America, typically found in deciduous and mixed woodlands, gardens, and areas with rich organic soil. The fungus emerges from an egg-like structure partially buried in the substrate, rapidly developing a spongy, white stalk topped with a dark olive-green gleba that produces a powerful fetid odor resembling rotting flesh. This smell typically attracts flies and other insects, which disperse the spores. <em>Phallus impudicus</em> is saprotrophic, obtaining nutrients by decomposing dead organic matter, and plays an important ecological role in nutrient cycling within forest ecosystems. Biological traits such as average lifespan, precise dimensions under field conditions, and detailed dietary preferences remain poorly documented in the scientific literature. The species is currently assessed as Least Concern by the IUCN, reflecting its broad distribution and apparent population stability across its native range. It has no known significant threats at the global level.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
