Biodiversity

The diversity of coral spreads across the sparkling water surface

In the bright shallow waters, a wide variety of corals crowd together and compete for growth.

Growth and destruction

What happens when rapidly growing corals get too big?

Table corals grow in colonies, overlapping each other.
Some corals even grow to enormous sizes.
Large corals can sometimes be affected by natural forces and break apart.

Death and rebirth

Over a long period of time, the coral has hardened into a rock.

The ocean floor is covered with finely broken coral skeletons.
Dead coral, regenerating coral, life cycle.
