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。

gray wolf

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。
