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。

Ochrolechia pallescensは、Ochrolechiaceae科に属する殻状地衣類で、絶滅危惧(EN)と評価されている。古い木の樹皮に生育し、長い生態学的連続性を持つ原生林の指標種とされている。絶滅危惧の状況は、生息域全体での老熟木と巨木の消失による深刻な衰退を反映している。
