Cladonia bellidiflora は北極高山地帯のコップ状地衣類で、酸性土壌や岩石上の基部鱗状層から赤い先端の子器柄が伸びます。北半球の北極および高山帯に分布しますが、南端の分布域では稀少です。気候温暖化、生息地の消失、限られた分布により、一部地域では絶滅危惧IA類（CR）に指定されています。

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
