地球上で生きたことが知られている最大の動物であるシロナガスクジラ（Balaenoptera musculus）は、体長33メートル、体重200トンに達することができ、心臓だけで小型自動車ほどの重さがあります。全ての海洋に生息し、極地の餌場と熱帯の繁殖地の間を回遊します。1日最大4トンのオキアミを摂取する濾過摂食者です。20世紀の捕鯨による絶滅危機からの回復後、世界的な個体数は10,000〜25,000頭と推定される絶滅危惧種です。

Clitocybe diatreta is a saprotrophic agaric fungus belonging to the family Tricholomataceae, found across temperate European forests and woodland habitats from Scandinavia southward through Central Europe. It typically fruits in autumn among leaf litter of deciduous and mixed forests, favoring moist, humus-rich soils beneath beech, oak, and conifer stands. The cap is convex to depressed, pale greyish-buff or whitish, with the decurrent gills and funnel-shaped profile characteristic of the genus Clitocybe. Microscopic examination reveals ellipsoid spores with smooth walls, confirming identity in this difficult taxonomic group. The diatreta species complex has been subject to taxonomic revision as molecular techniques clarify boundaries between morphologically similar taxa. As a decomposer of forest litter, C. diatreta contributes to the breakdown of cellulose and lignin in temperate forest floors, releasing nutrients back into the soil ecosystem. Its presence indicates structurally diverse, undisturbed forest conditions preferred by many specialist saprotrophic fungi in European woodland communities.
