Cheetah

地球上で最も速い陸上動物で、アフリカとイランの草原において短距離走で時速112kmに達する。深い胸部、長い脚、独特の黒い涙縞模様を持つ細身の体型が特徴だ。他の大型ネコ科動物とは異なり、チーターはチャープ音やパー音で鳴く。生息地の分断と大型捕食者との競争により、残存個体数は約7,000頭のみとなっており、危急種に分類されている。

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。
