Insects work in harmony, timing their calls to fall between the notes of others. 昆虫鸣得很和协, 他们按照时间规律来互相传达着信息
The calls of the siamang gibbons begin as a duet between the dominant male and female. 合趾猴通过叫声来联系公猴和母猴
until now the land between them has been reduced to spires and pinnacles. 直到把其间的土地削凿成 今天这样的尖峰和石塔
These spires are the eroded remains of an ancient seabed that once stretched between the two continents. 曾经连接两块大陆的古老海床 侵蚀后留下了一座座尖耸的山峰
