What is the Key West Coral Reef Made Of?
The Key West coral reef is a complex eco-system and one of the most diverse in world. It is the equivalent of the of the tropical rainforests on land, and is the home to more than a fourth of all known fish species, despite only being less than one percent of the marine environment.
Coral reefs have been around for approximately 200 million years, and some scientist even believe up to 400 million years ago they existed. The coral reefs take time to grow and it is believed they reached their level of biological diversity about 50 million years ago.
Coral reef is made up of thin layers of calcium carbonate that has been secreted over thousands of years by tiny soft-bodied animals by the billions called coral polyps. These polyps differ in sizes and can be as small as a pinhead to a foot in length, and each one lives in a symbiotic relationship with an algae. This algae, called Zooxanthellae, gives the coral its beautiful hue by taking in Carbon Dioxide, then giving off Oxygen. These millions of polyps start to form on the limestone that exist, and then create what we now know as a coral reef.
