Common Eyelash

The Common Eyelash (<em>Scutellinia scutellata</em>) is a small cup fungus belonging to the genus Scutellinia within the family Pyronemataceae. It is recognised by its distinctive scarlet to bright red disc-shaped fruiting body, typically measuring just a few millimetres across, and fringed with dark brown hair-like structures resembling eyelashes, from which its common name derives. This species is native to Asia and Europe and North America, and typically inhabits decomposing wood, moist soil, and other organic substrates in humid environments. Its geographic range is wide, with confirmed records across Asia including Taiwan, Europe including Belgium, Denmark, Norway, and Portugal, North America including the United States, and South America including Brazil. <em>Scutellinia scutellata</em> is assessed as Least Concern on the IUCN Red List, reflecting its broad distribution and apparent abundance. Biological traits such as lifespan, size, and specific dietary habits remain poorly documented in the scientific literature, though as a saprotrophic fungus it typically obtains nutrients by decomposing dead organic matter.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
