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。

Peniophorella echinocystis は絶滅危惧IA類（CR）と評価された皮質性菌類で、極めて稀少で分布域が非常に限定されている。成熟した老齢林や古代林の枯れ木に薄い伏生の皮膜を形成する。この絶滅寸前の状況は、立ち枯れや倒木のある老齢林の緊急な保全の必要性を強調している。
