Corals Need
THREE things to survive! The three things are
WARM WATER,SUNLIGHT,CLEAR and SHALLOW WATERS. Corals will also not grow in waters
lower than 68 DEGREES FARENHEIT (20 DEGREE CELSIUS ).. The warm nad shallow water is needed because it contain ZOOXANTHELLAE that transfers food energy to the corals.

Did you know that singapores also have coral reefs?
Coral Reefs In SingaporeThere were once over 60 offshore islands and patch reefs around Singapore, most of which were situated south of mainland Singapore. However, since the mid 1970s, major land reclamation was carried out on the mainland as well as the offshore southern islands. Most of the southern islands were reclaimed, adding 1695 ha to Singapore's total land area. Some islands were merged as a result. The reef flats of many islands e.g. Pulau Sudong, Pulau Hantu and Kusu Island were reclaimed right up to the reef slope. Many of the coral reef organisms were smothered by the reclamation, while others were severely affected by the resulting increase in water turbidity. Since 1986, most coral reefs in Singapore have lost up to 65% of their live coral cover

Amazing, Beautiful Corals
Did You Know..
Australia's great barrier reef is over 2,000 miles long and that happen to be the largest living stuctures on Earth and they have lived for over 100 MILLION years! Without reefs, many shoreline commuinities would have been underwater by now! On average, every square metre of reefs protects $47,000 from storm damage and erosion.

Did you know that coral reefs take up less than 1% of the ocean floor, yet 25% of the marine life lives on the reefs. A reef can be tiny and yet inhabit 3,000 species. Imagine man taking away a huge reef, what would happen to the poor marine creatures?
