Coral reefs are formed by colonies of tiny creatures called polyps. Each of the polyps deposits limestone in a design specific to its species. As the colony grows, the limestone formation becomes larger.
Stretched beside the chain of Florida Key Islands is a ribbon of coral, America’s longest barrier reef. Barrier reefs lie between the water near the shore and the open sea, protecting the mainland.
The reef along the Florida Keys is possible because of the warm flow of the Gulf Stream. Coral reefs need water above 70°F. Since reef coral needs some food manufactured by algae, there also has to be enough light to permit algae to grow.
Coral reefs are composed of stony coral, like brain coral, mushroom coral, star coral, and staghorn coral, that anchor themselves to the seabed. Other organisms, such as sponges, sea cucumbers, algae, and protozoans, then fill up gaps and bind together sections of coral. The growing reef structure provides a habitat for marine plant life, fish, and shellfish.
Coral reefs are living organisms created over the course of thousands of years. Physical contact by humans and water pollution can weaken a section of living reef. The cumulative devastation can be enormous.
