| [00:00.0] | Of all the formations in the Pacific, |
| [00:02.69] | these reefs are by far the richest in life |
| [00:06.79] | There are hundreds of different kinds of coral |
| [00:09.81] | And all are made up of millions of tiny creatures called polyps, |
| [00:14.69] | each covered in a hard skeleton |
| [00:17.28] | Reefs are home to thousands of specialists, |
| [00:19.92] | like these razorfish that blend into the staghorn coral around them |
| [00:24.75] | But not all animals here need to blend in |
| [00:28.51] | Grey reef sharks |
| [00:30.60] | The reef's top predators, |
| [00:32.43] | these sharks patrol the waters on strong currents |
| [00:35.80] | But without all the life on the reef here, |
| [00:38.32] | they could never exist in such numbers |
| [00:40.88] | They may be idle right now, |
| [00:42.92] | but they won't remain this way for long |
| [00:46.26] | As night falls, it's feeding time |
| [00:50.63] | Needlefish stalk the coral shallows in search of food |
| [00:54.49] | Predators by day, at night they become the prey |
| [01:00.6] | Speeding away at 20 miles an hour, |
| [01:02.85] | the needlefish give the chasing sharks a run for their money |
| [01:06.1] | But it's hard to escape from so many |
