Tim Laman - Dreamlike Coral Reefs

There are a lot of coral reefs in the shallow sea of tropical and subtropical areas. After corals die, their calcareous skeletons will be deposited. Their offspring grow on these skeletons and after long-term accumulation, coral reefs are finally formed. On the colorful coral reefs, there are also many kinds of marine organisms living. Coral reefs also attract diving enthusiasts, tourists and photographers from all over the world.
