相信很多人到亞洲熱帶雨林區的時候,都會被大長臂猿的聲音吸引住。仔細一看。牠們的喉部有一個囊狀構造,並與喉腔相通,因此可以產生共鳴,聲音的嘹亮程度絕對不輸給世界級聲樂家喔!而鳴叫最大的意義為「這是我家,你們最好不要進來~」,一起來聽聽牠們的大合唱吧!“You shall not pass!!!” This is what Siamangs howl in Asian Tropical Rainforest Animal Area at Taipei Zoo. Siamangs are extremely territorial animals, therefore by vigorous vocal display, they are defending their residence!
