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。

Nostoc calcicolaは、湿った石灰岩岩盤表面、土壌、石垣にゼラチン状の濃緑色から黒色に近いコロニーを形成する糸状の窒素固定シアノバクテリアである。温帯および地中海地域、特にカルシウム豊富な基質を持つ湿潤生息地に分布する。危急種に分類されるこの種は、生息地の消失、都市開発、石灰岩岩盤微小生息地の劣化により脅威にさらされている。
