Definition: Coral reefs are underwater structures made from calcium carbonate secreted by corals. Corals are colonies of tiny living animals found in marine waters containing few nutrients. Most coral reefs are built from stony corals‚ and are formed by polyps that live together in groups. The polyps secrete a hard carbonate exoskeleton which provides support and protection for the body of each polyp. Reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. Often called “rainforests

necessary symbiotic relationship with coral‚ zooxanthellae also serve as the component responsible for the lush and vibrant colors of the coral reefs. A good indication of whether or not a reef is healthy is the amount of color present. Since the algae contains photosynthetic pigments‚ the degree of light it receives can alter the colors‚ hence the colorful reefs. The algae are sensitive to light and temperature‚ and expel zooxanthellae cells when they undergo conditions that place stress on them‚ such

Coral Bleaching Coral reefs deliver ecosystem services to tourism‚ fisheries and shoreline protection and often called “rainforests of the sea”. Most coral reefs are built from stony corals‚ which in turn consist of polyps that cluster in groups. Coral reefs grow best in warm‚ shallow‚ clear‚ sunny and agitated waters. However‚ coral reefs are fragile ecosystems‚ partly because they are very sensitive to water temperature. They are under threat from climate change‚ oceanic acidification‚ blast

The island consists of inhabited dense forests which total up to approximately 8 296 hectares and numerous coral reefs housing diverse marine life. As a large group‚ we broke up into 4 sub-groups and conducted our individual coastal survey studies while following a pre-discussed plan of assessment. Our surveys involved the use of 50cm x 50cm quadrats with a 5x5 grid
