咸水与淡水不同 不会溶解石灰岩 - so most sea caves are created by the mechanical pounding of the waves.
所以大部分海洋洞窟 是在海浪的机械冲击下形成的 - The rocky outcrops of New Zealand's Poor Knight Islands are riddled with sea caves
新西兰坡·骑士岛的 岩礁下布满了海蚀洞 - and just like those in Borneo
与婆罗洲的洞窟一样 - they have become important shelters for many species.
它们也成了许多动物的重要庇护所
