these reefs are by far the richest in life
There are hundreds of different kinds of coral
And all are made up of millions of tiny creatures called polyps,
each covered in a hard skeleton
Reefs are home to thousands of specialists,
like these razorfish that blend into the staghorn coral around them
But not all animals here need to blend in
Grey reef sharks
The reef's top predators,
these sharks patrol the waters on strong currents
But without all the life on the reef here,
they could never exist in such numbers
They may be idle right now,
but they won't remain this way for long
As night falls, it's feeding time
Needlefish stalk the coral shallows in search of food
Predators by day, at night they become the prey
the needlefish give the chasing sharks a run for their money
