Since those earthquakes, there's been another big change here.

自从地震后，这里发生了另一个大变化

At the end of the last ice age, large areas of this landscape became flooded as the ice melted.

But here, it evolved into a harmless, graceful⁴ wanderer.

在这里它进化成了一个无害的优雅的漫游者。

Jellyfish normally feed on small fish.

水母通常以小鱼为食

But in the lakes, there was little prey⁵.

但在湖里，猎物稀少。

So their bells have become a home to millions of tiny photosynthesising algae⁶.

which in turn provide their hosts, the jellyfish, with food.

Now, each day, the jellyfish migrate across the lake, following the arc of the sun.

Their only obstacle, the occasional anemone⁷ that tries to catch them as they float past.

它们唯一的妨碍就是在游荡时偶尔银莲花会试图捕获它们

And sometimes fails. So with little danger, and a never-ending supply of food,

有时会失败。因为危险很少而食物无限供应，
