A macro view of hard coral in Malaysia is seen here. Corals are marine organisms that often live in colonies of many identical individuals. Coral is formed from a myriad of polyps, which can be a few millimeters in diameter. They are genetically identical and reproduce asexually, but can also breed by spawning.

Many species need sunlight to grow and are found in shallow water, though other species can live in the deeper, colder waters.
