Symbiosis and Competition

The wrasse, a small marine fish, periodically cleans harmful parasites from the mouth and body of the moray eel. The moray, in turn, protects the wrasse from larger predators and provides it with a constant supply of food. This is an example of the type of relationship known as

• mutualism

• parasitism

• commensalism

• predation
