There are many types of relationships that are in the Ocean Reef. Today I am going to tell you a few. The first relationship is parasitic which is when (1 animal benefit,and 1 is harmed). An example of this is included with a sperm whale and krill. The 2nd type of relationship is mutualistic which is when (2 animals benefit). An example of this is used with a clownfish and a anemone. The last type of relationship is communalistic which is when (1 animal benifits, and 0 are harmed). An example of this is with algae.
