Coral has the ability to control the amount of zooxanthellae in their tissues by emanation it; this process is normal and is called coral bleaching. However, when corals are immoderately stressed, this well-formed cases them to expel more zooxanthellae than necessary, and theref ore loss of colouring results from the eli! sion of too much zooxanthellae, and/or the concentration of photosynthetic pigments in these organisms are diminished(www.marinebiology.org) Long term bleaching can realize the partial or total death of coral colonies, entirely if the situation...
