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。

wild cat

ヨーロッパヤマネコ（Felis silvestris）はIUCNレッドリストで絶滅寸前（CR）に分類されています。深刻な個体数減少と生息地の消失により、野生での絶滅の極めて高いリスクに直面しています。
