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。

Clustered yellowtops

Flaveria trinervia, commonly known as clustered yellowtops, is a fast-growing annual herb in the family Asteraceae. Native to tropical and subtropical regions, it has a remarkably wide distribution spanning Africa, Asia, Europe, and the Americas, where it thrives as a pioneer species in disturbed habitats, roadsides, agricultural margins, and waste ground. The plant typically reaches 30–90 centimeters in height, producing lance-shaped leaves arranged oppositely along branching stems. Its small yellow flower heads are clustered in dense corymbs, giving the species its common name. Flaveria trinervia is notable among plants for utilizing C4 carbon fixation, an efficient photosynthetic pathway that enables rapid growth under warm, high-light conditions with limited water. This metabolic adaptation contributes to its success as a colonizer across diverse tropical and warm-temperate environments. The species is considered Not Evaluated by the IUCN, reflecting its wide range and apparent abundance rather than any formal assessment. Seeds are dispersed by wind, facilitating its spread into new territories. Though not a major agricultural weed, it can establish in cultivated fields. The genus Flaveria, comprising around 23 species, is studied extensively by plant biologists for insights into the evolution of C4 photosynthesis from ancestral C3 pathways.
