One of the things that really worries me, when I talk about this, is the fate of biodiversity in the deep ocean.

其中一个当我说到它就非常担心的是，深海生物多样性的命运。

The deep sea creature you see lives thousands of feet underwater, and it looks a lot less globular down there, where water pressure is more than 100 times stronger than the air pressure we experience on land.

你到的这种深海生物生活在数千英尺深的水下，在那里，它起来并没有那么臃肿，那里的水压比我们在陆地上经受的大气压力强100多倍。

Fancy cameras on remote-operated vehicles, for instance, allow scientists to make laser scans of deep-sea creatures such as jellyfish without removing them from their habitat.

例如，科学家可以远程操作车辆上的高级摄像机，对水母等深海生物进行激光扫描，而无需将它们从栖息地移走。

Unlike most other fish, the ones that live in these depths don't have gas-filled cavities like swim bladders that would collapse under the extreme pressure.

和其它鱼不同，生活在深海中的生物没有空气囊，即鱼鳔儿，鱼鳔会被强大压力破坏。

Because creatures of the deep ocean have evolved to tolerate so much pressure, their cell membranes tend to liquefy when that pressure is released.

因为深海生物已经进化得能够耐受如此高压，一旦压力消失，它们的细胞膜就会溶解。

A study it conducted a few years ago concluded that 75 percent of deep sea organisms produce their own light.

几年前的一项研究发现，75%的深海生物携带发光物质，会发出亮光。

Although more than 90% of deep-sea creatures are bioluminescent, only one group produces the color red: dragonfishes.

虽然超过 90% 的深海生物会发光，但只有其中一种可以发出红色的光，即是巨口鱼。

Much of the life in the shallows probably perished as the growing ice sheet locked up

而罹难，但为何还有那麽多深海生物也步上後尘？

Helena just finished reading an informative book about sea creatures that live in the deepest part of the ocean.

Helena剛剛讀完一本內容豐富，關於生活在深海的海洋生物的書。

This creates a warm environment of all kinds of weird and wonderful creatures, including vent mussels, tube worms and blind 'yeti crabs', so called because of their hairy claws, some of which get cooked because the water is so hot.

这为各种怪异又奇妙的生物创造出一个温暖的环境，这些生物包括深海热泉附的贻贝、管虫和完全没有视觉功能的“雪人蟹”，由于其毛绒绒的螯而被叫做雪人蟹，因为水太热，其中一些雪蟹被煮熟了。

Those one or more years old are benthic, meaning they live near the bottom.
