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。

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
