[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
