CORAL REEFS
Almost every one of us have heard and most of you have seen the Coral reefs but did you know what actually these are:
As a mariner its important to know about the marine life, that was one reason I have chosen this topic for my today's short presentation.
GM, my scheme of presentation will be as flashed:
DEFINATION OF CORAL REEF
DIFFERENCE BETWEEN CORAL AND CORAL POLYP
WHERE WE CAN FIND CORAL
CONSTRUCTION OF CORAL REEFS
CONDITIONS FOR GROWTH OF CORAL REEFS
TYPES OF CORAL REEFS
THREAT TO CROAL REEFS
WHAT SHOULD A MARINER DO IN CORAL RICH AREAS
FUTURE OF CORAL REEFS
CONCLUSION
What is a coral reef?
Coral reefs are huge structures made of limestone that is deposited by living things. There are thousands of species that live in coral reefs, but only a fraction actually produces the limestone that builds the reef. Coral reefs support over 25% of all known marine species. They are one of the most complex ecosystems on the planet, and are home to over 4,000 different types of fish, 700 species of coral and thousands of other plants and animals.
A good way to imagine a coral reef is to think of it as a bustling city or community, with the buildings made of coral, and thousands of inhabitants coming and going, carrying out their business. In this sense, a coral reef is like a metropolis under the sea.
What is coral?
Although coral is often mistaken for a rock or a plant, it is actually composed of tiny, fragile animals called coral polyps. When we say "coral" we are actually referring to these animals and the skeletons they leave behind after they die.
Although there are hundreds of different species of corals, they are generally classified as "hard coral" or "soft coral".
Hard corals grow in colonies and are the architects of coral reefs. They include such species as brain coral and elkhorn coral. Their skeletons are made out of calcium carbonate (also known as limestone) which is hard and eventually becomes rock. Hard
