Picture the ocean as a city. While not a technologically developed metropolis, the population of the ocean far exceeds that of any modern city. The quiet, serene shore waters are the "suburbs." As depth extends, activity increases and pace accelerates. The currents create natural highways with infinite traffic. When the currents converge, flowing together around continents and sea boards, they reach their final destination. This is the metropolis, the agora, the forum, the fundamental locale of all activity- coral reefs.
Throughout the world, coral reefs have been prime sites of biodiversity featuring all types of animals from ominous sharks to primitive phytoplankton. There is also a wealth of plant and bacterial growth. Amidst plentiful and indefinite activity, sponges take their own role in the underwater society. As porifera provide a safe haven for microorganisms, they are supporting the ocean's balance.
For those not completely acquainted with the dynamics of a coral reef, read on for some more basic knowledge. Coral are animals classified as coelenterates of cnidarians, belonging to the class Anthazoa. Developing in colonies, coral are organisms with calcareous skeletons and a soft body. When the organisms perish, the skeletons with deposits of calcium carbonate and magnesium create the basis for coral reefs. As algae, anemones, microorganisms, sponges, and other primitve creatures accumulate, more advanced organisms also inhabit the coral reefs. With the current directing organisms towards the reef, its dimensions consistently multiply. In a matter of time, reefs such as the Great Barrier Reef develop.
Unfortunately, human activities, including pollution and overfishing, are inflicting detrtiment upon coral reefs. The crown star fish is capable of destroying coral reefs. Some compounds excreted by sponges actually are severely toxic to fish, fungi, and other organisms. Currently, several human organizations are endeavoring on behalf of coral reefs. There are several coral reef campaigns throughout the world. Legislation has also been passed. In addition, the United States military has converted out of date army tanks into artificial reefs. Nevertheless, porifera have been contributing to coral reefs for millions of years, and their methods are definitely efficient.
