The coral reef in the world

Reefs are only in the Tropical seas and cover a total of approximately 600,000 km2. The areas with the largest reefs are three:

  • the Caribbean
  • the western islands of the Indian Ocean
  • the Asian-Pacific area.

The latter area is the richest in corals species, with peaks in the Indonesian islands, the Philippines and Northern Australia, while the Indian Ocean and the Pacific have fewer species. There is no relation between the number of coral species and the size of the reef; most of the massive reefs and atolls of Polynesia consist of less than fifty species, versus over five hundred in the Borneo or the Philippines.
