jaguar

アメリカ大陸最大のネコ科動物で、体重は最大100kgに達し、がっしりとした筋肉質の体型と特有のロゼット模様の毛皮を持つ。メキシコから南アメリカにかけて分布し、アマゾンやパンタナルが主要生息地となる。優れた水泳能力を持つ頂点捕食者であり、獲物個体数の調節に重要な役割を担う。森林破壊により生息域が縮小し、準絶滅危惧に分類されている。

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。
