Coral Reefs are found throughout tropical and subtropical oceans in the Indo-Pacific and Atlantic, normally between the Tropic of Capricorn and Tropic of Cancer (30ºS, 30ºN latitude). However, they also occur outside this range where warm water currents travel outside this band, as is the case where the Gulf Stream Current brings warm tropical water from the Caribbean north to the islands of Bermuda.
Coral reefs have been formed since the last of three glacial periods in the Pleistocene epoch, 10,000 years ago. Seawater trapped as ice in enormous glaciers caused sea level to fall. Consequently, all previously formed coral reefs probably died from exposure. When the glaciers melted, sea level rose to its current position and present-day reefs began to develop.
Coral Reefs are estimated to cover only 0.1% of the Earth’s surface, about 235,000 sq miles, and are within depths less than 100 ft. Their distribution is strongly influenced by the environmental preferences of the coral animals.
