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。

Chocolateweed

Chocolateweed (Melochia corchorifolia) is a pantropical annual or short-lived perennial herb in the family Malvaceae, widespread across tropical and subtropical Asia, Africa, the Pacific islands, and Australia. It is a common weed of disturbed and agricultural habitats including rice paddies, riverbanks, roadsides, and field margins, tolerating a wide range of soil types including waterlogged and saline conditions. The plant grows to 40–100 centimetres, producing alternate, toothed leaves and small pink to purplish flowers followed by rounded, ribbed capsule fruits. The stem fibres of Melochia corchorifolia are used traditionally in parts of Asia and Africa as a substitute for jute in making rope, matting, and rough textiles, reflecting the plant's membership in the mallow family which includes many fibre-producing species. The seeds and young leaves are edible in some cultures and the plant has uses in traditional medicine. Despite its status as an agricultural weed, it also provides nectar for bees and other insects. The IUCN classifies it as Least Concern, reflecting its widespread and abundant distribution across tropical agricultural landscapes worldwide. Its success as a coloniser of disturbed habitats suggests high resilience to anthropogenic change.
