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。

giraffe

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
