The dolphin, as so often, are working as a team, synchronizing their attacks, to confuse their prey.

As dawn approaches, squid and fish and plankton retreat downwards, to shelter in the darkness.

黎明来临，鱿鱼、鱼和浮游生物再次下沉隐没在黑暗中。

Some of these isolated volcanoes rise as much as nine thousand meters from the sea floor, reaching close to the surface.

有一些成为孤岛的火山高耸在海床上达9000米，几乎快要到达海面了。

Around these peaks invigorated by daily sunshine

这里的日照非常充足，

marine life flourishes in spectacular abundance.

海洋中的生物在这里大量繁荣。

Fish crowd here,

鱼类在这里大量汇聚，

because the volcano forces nutrients to the surface, encouraging the plankton to bloom.

因为火山迫使洋流把海底的养分送上水面，使得浮游生物十分旺盛。
