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 Cottonwood

<em>Populus deltoides</em>, commonly known as common cottonwood or eastern cottonwood, is a large, fast-growing deciduous tree in the family Salicaceae. It is native to North America but has been widely planted and naturalized in Africa, Asia, Europe, and South America. Common cottonwood typically grows along rivers, streams, floodplains, and other moist bottomland habitats, where it can reach heights of 30 meters or more. The species is named for the cottony white fibers attached to its seeds, which are released in massive quantities in early summer and can create a snow-like appearance in the landscape. Its triangular, toothed leaves flutter characteristically in the slightest breeze due to their flattened petioles. Cottonwood is an important riparian tree providing habitat for birds, insects, and mammals. Biological traits of this species remain poorly documented in the scientific literature.
