Massive, region-wide decline of corals across the entire Caribbean basin have been reported, with the average stony In turn, coastlines currently protected by reefs would more readily flood during storms, some islands and low-lying countries would vanish under the water, and the $30 billion industry that coral reefs provide could collapse. Coral reefs teem with life, covering less than one percent of the ocean floor, but supporting about 25 percent of all marine creatures. The mutualistic symbiosis between corals and zooxanthellae is a well-known fact amongst aquarists. It's possible this technique could help rebuild the reef and make the coral more likely to survive bleaching events. A healthy coral reef, Hardy Reef in Queensland, Australia. Scientific name. taxonomic . Coral reefs are unique (e.g., the largest structures on earth of biological origin) and complex systems.

The coral species that build reefs are known as hermatypic, or "hard," corals because they extract calcium carbonate from seawater to create a hard, durable exoskeleton that protects their soft, sac-like bodies. At their base is a hard, protective limestone skeleton called a calicle, which forms the structure of coral reefs. For example, the humphead wrasse, Cheilinus undulatus Rüppell 1835, was described by Eduard Rüppell, a German naturalist, in 1835. They have a yellow or yellowish-green dorsal body with pointed and rounded scales with black edging. It is the dominant coral species on reef slopes at depths of less than 10 feet (3 m), but can also be found to 90 feet (27 m) or more.
