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。

Cobble Forget-me-not

Cobble forget-me-not (Myosotis schistosa) is a small annual or biennial herb in the family Boraginaceae, native to riverine and coastal habitats in parts of Europe, particularly associated with slate, shale, or schist substrates and disturbed gravelly or rocky ground. Like other Myosotis species, it bears the typical small, five-petalled blue flowers with a yellow eye that give forget-me-nots their widespread recognition. The genus Myosotis encompasses dozens of species distributed across Europe, Asia, North America, and the Southern Hemisphere, many of which are adapted to specific, often nutrient-poor or geologically specialised substrates. Cobble forget-me-not is assessed as Data Deficient by the IUCN, reflecting limited information on its distribution, population size, and ecology. Botanical surveys in appropriate habitats across its inferred range—particularly slate-rich riverbanks and coastal cobble in Europe—are needed to clarify its taxonomy, distribution, and conservation requirements. Like many small annual herbs in disturbed habitats, it may be locally common in suitable microsites but easily overlooked due to its small size and annual habit.
