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。

Echinoderma calcicolaはヨーロッパの石灰質草原や林縁で育つ中型のキノコで、淡色の笠に暗色の尖った鱗片が覆われ、柄も同様に装飾されています。古くから種の豊富な石灰質生息地の指標種とみなされています。絶滅危惧（EN）に分類されており、農業の集約化と石灰岩草原生息地の喪失により深刻な脅威にさらされています。
