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。

Common eyebright

The Common Eyebright (<em>Euphrasia nemorosa</em>) is a small annual plant belonging to the genus Euphrasia within the family Orobanchaceae. This species is a hemiparasite, typically attaching its roots to the roots of neighbouring grasses and other plants to obtain water and nutrients, while also performing photosynthesis. It is often found in diverse terrestrial habitats ranging from tropical forests to temperate regions, including grasslands, heathlands, and woodland margins. Geographically, <em>Euphrasia nemorosa</em> is distributed across Europe, with confirmed records in countries including Belgium, Denmark, Finland, and France, as well as presence in North America in Canada and the United States. The species is assessed as Least Concern on the IUCN Red List, indicating a stable global population without immediate threat of extinction. Biological traits of this species remain poorly documented in the scientific literature, including specific data on lifespan, body size, and diet. The common name "eyebright" reflects its historical use in herbal medicine for treating eye ailments, though this application is not supported by modern clinical evidence.
