Epaulard

イルカ科で最大の種であるシャチ（Orcinus orca）は体長最大9メートル、体重6トンに達し、北極から南極まですべての海洋に生息しています。独特の方言、狩猟戦略、集団間で異なる文化的伝統を持つ母系ポッドで生活する頂点捕食者です。一部の集団は魚類を、他の集団は海洋哺乳類を専門に捕食します。天敵はなく、シャチは生息するすべての海洋食物連鎖の頂点に位置します。

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。
