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 Forget-Me-Not

<em>Myosotis arvensis</em> is an annual or biennial herbaceous plant in the family Boraginaceae, order Boraginales, commonly known as the field forget-me-not or common forget-me-not. The species is classified as Least Concern on the IUCN Red List, with widespread stable populations. <em>Myosotis arvensis</em> has a cosmopolitan distribution, recorded across Africa, Asia, Europe, North America, Oceania, and South America, where it has been widely naturalized beyond its native European and West Asian range. The plant typically grows in disturbed habitats including arable fields, roadsides, gardens, hedgerows, and open woodland, tolerating a broad range of soil types. It produces characteristic small, sky-blue five-petaled flowers with a yellow center, borne on curved, scorpioid cymes that straighten as the flowers open — a feature typical of the borage family. The plant typically reaches 15 to 40 centimeters in height and is covered in soft, spreading hairs. Biological traits of this species remain poorly documented in the scientific literature.
