These injuries should be carefully observed, as necrotic tissue provides a perfect environment to culture serious soft tissue infections. This extraordinary ability of mating with other sub-species is considered by many to be one of the several queen angelfish adaptations for survival. Bleaching not only has the power to destroy coral entirely, it can also drastically slow down its development. To learn more, visit our Earning Credit Page. The zooxanthellae, via photosynthesis, are capable of transforming water and carbon dioxide into carbohydrates and oxygen. They are often found in schools of hundreds or even thousands, and besides their unique coloring, they are know for their unique reproductive strategies and adaptations in the science world.
