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。

Usnea cornutaはParmeliaceae科の果状地衣類で、準絶滅危惧(NT)と評価されています。樹木の枝や小枝に垂れ下がる茂み状の葉状体を形成し、主に湿潤な森林環境に生息します。すべてのUsnea属の種と同様に大気汚染、特に二酸化硫黄に対して非常に敏感で、大気質の有用な生物指標として利用されます。
