Symbiotic Relationships in Coral Reefs | Sciencing
This relationship exists between Hermatypic (reef-building) corals and zooxanthellae or Clown fish and Anemones also exhibit mutualism. Coral reef ecosystems are teeming with symbiotic relationships. mutually beneficial symbiotic relationships with clown fish and anemone fish. An example of predation in the coral reef, involves the saddled butterflyfish and the sea anemone. Clownfish protect the anemone against their.Copperband Butterfly Fish for Aiptasia Anemone Control
Many seaweeds also have chemical weapons that can damage and kill coral, allowing seaweed to take over an area more easily.

While there are a number of reasons for these losses pollution and ocean acidification and warmingremoval of herbivorous fish through overfishing either through directly removing these species or through trophic cascades is one that is commonly overlooked.
Green seaweed that has taken over a large portion of the Great Barrier Reef in Australia. Researcher Dixson and Hay recently found that this mutualistic relationship is even more interesting than we originally thought. A juvenile Gobidon fish is shown on an Acropora coral. These fish spend their entire lives with the same coral, and protect the coral from encroaching seaweed.
Joao Paulo Krajewski source: They demonstrated that when a toxic seaweed or just the toxic chemical from the seaweed made contact with coral, the coral released a chemical odor that caused gobies to immediately come to the rescue and trim the nearby seaweed.

One of the goby species even consumed the toxic seaweed and had the added benefit of becoming more toxic itself and thus less desirable to its own predators. The mutualistic fish Gobidon histrio in its home coralAcropora nausuta, coming out to investigate the presence of the toxic green alga Chlorodesmis fastigiata.
Inside each coral polyp lives a single-celled algae called zooxanthellae. The zooxanthellae capture sunlight and perform photosynthesis, providing oxygen and other nutrients to the coral polyp that aid in its survival. In turn, the zooxanthellae is provided with the carbon dioxide expelled by the polyp that it needs to undergo photosynthesis. The presence of the zooxanthellae also provide colored pigments to help protect the coral's white skeleton from sunlight.
This is a mutual symbiotic relationship that is beneficially to both participants. Using the coral skeleton as a place to anchor, these sessile, or stationary, organisms provide shelter for fish shrimp, crabs and other small animals. In both cases, the symbiosis is commensal.

Sciencing Video Vault Sea anemones are also common sessile residents of coral reef. Sea anemones are known for their mutually beneficial symbiotic relationships with clown fish and anemone fish. The tentacles of the anemones provide protection for the fish and their eggs while the anemone fish protects the anemone from predators such as the butterfly fish.
