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。

Xylaria corniformisは熱帯および亜熱帯林生息地の腐朽木材に硬く角状またはシカの角状の黒い子座を形成する棍棒形の炭質子嚢菌類です。森林生態系において木質セルロースの分解に貢献する腐生性木材分解菌です。絶滅危惧（EN）に分類されており、熱帯の森林破壊と原生林生息地の消失が脅威となっています。
