Bornean orangutan

世界最大の樹上性哺乳類であるボルネオオランウータン（Pongo pygmaeus）は最大90kgの体重でボルネオ島の熱帯雨林の林冠で生涯のほとんどを過ごします。単独生活をする半遊牧的な動物で、木に夜間の睡眠巣を作り、果実、葉、無脊椎動物を採食します。パーム油拡大による森林伐採と密猟により、過去60年で個体数が50%以上減少した深刻な絶滅危惧（CR）種です。

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。
