Where are the coral reefs?
Owing to the presence of photosynthetic symbiotic algae, distribution
of reef-building corals is mainly controlled by sea water temperature
and light intensity. Other important factors include substratum type,
water flow and water quality. Coral reefs are found only in tropical
and subtropical waters, mostly in shallow waters of depth less than
30m and on both sides of equator up to 25¢X North and South latitude.
