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。

Pool Frog

Pool Frog（Pelophylax lessonae）はIUCNレッドリストで絶滅危惧IA類（CR）に分類される。深刻な個体数の減少と生息地の損失により、野生での絶滅の危険性が極めて高い状態にある。
