洞穴 7

The droppings also support other types of cockroaches which spend part of their day resting on cave walls. These in turn become food for giant cave centipedes, some more than 20 centimetres long. Bizarrely, there are crabs here, too, sifting through the droppings for nutrients. All these animals spend their entire lives within the cave. They're totally dependent on the digested remains of food that's brought in from outside. Each evening in just two hours, 3 million bats leave the safety of the cave to hunt for insects in the forest outside. But not all will return. As they leave the cave the stream of bats form a doughnut-shaped ring. The wheeling bats seem to confuse a rufus-bellied eagle, but they must still survive the attacks of other, more specialised, birds of prey.

这些掉落物还是其他种类的蟑螂的食物来源，它们有一部分时间是在岩壁上度过的。这一切又为岩洞中的另一种大型洞穴蜈蚣提供了食物，这种动物有时可以长达20厘米。令人称奇的是，这里还有螃蟹，它们从掉落物中寻找养份。这些动物终生在洞穴中生活。它们完全依赖于蝙蝠从洞外吃进去消化之后的剩余物来生活。每天晚上，这300万只蝙蝠有两个小时的时间飞离安全的洞穴，到外面的森林里去捕捉昆虫。但并不是所有蝙蝠都会平安归来。离开洞穴时，蝙蝠群形成了一个面包圈一样的队形。这些旋转滚动的蝙蝠似乎让这些棕腹隼雕晕头转向，但还有别的威胁等待着它们，那些专吃蝙蝠的鸟类。
