This is the gorilla stop in the forest gallery of the Animal Kingdom Grand Adventure Exhibition. Listen here to how chest-beating becomes a language in the tropical rainforest.

你看！眼前正在搥胸的大猩猩，牠來自枝葉茂密、熱氣蒸騰的非洲熱帶雨林深處。
大猩猩招牌的捶胸動作，其實並不是憤怒或興奮的表現，而是猩猩間的共通語言，利用從脖子延伸到胸腔的喉氣囊共振來傳遞訊息，其他大猩猩聆聽到「咚咚」的搥胸聲，就能精確知道對方的體型和資訊。
大猩猩與人類之間除了基因非常相似，還一樣講究儀式感，有獨特的睡前儀式。牠們會花時間利用樹枝和葉子編織出一個碗狀的睡巢，而且每天都要睡新的巢。即使隔天活動的範圍再小，也絕對不重複使用，除非是環境中的搭建材料不足。這個習慣讓牠們在潮濕悶熱的雨林中，降低了寄生蟲與傳染病感染的機率，被遺棄的舊睡巢也會分解，回歸大自然。
地球的雨林正快速消失，加上不法盜獵猖獗，守護大猩猩，也是為地球的生態與氣候守護未來。
Look! The gorilla before you is beating its chest. It comes from the deep, steaming, leaf-thick heart of the African tropical rainforest.
That famous chest-beating is not anger or excitement. It is a shared language among gorillas. A laryngeal air sac that runs from the neck into the chest cavity resonates to carry the message. When other gorillas hear the boom, they can tell, with precision, the body size and the information of the one who struck.
Gorillas are not only genetically very close to humans; they also care about ritual, including a distinctive bedtime rite. They take time to weave a bowl-shaped nest from branches and leaves, and they sleep in a new nest every night. Even if the next day's range is tiny, they will not reuse a nest unless building materials in the environment run short. The habit lowers the chance of parasites and infection in the damp, stifling rainforest. Abandoned nests break down and return to nature.
Earth's rainforests are vanishing fast, and illegal poaching is rampant. To protect the gorilla is also to protect the future of the planet's ecology and climate.
