Commensalism
Coral polyps and Zooxanthellae. They have a symbiotic relationship with each other. The coral polyps provide a home for the Zooxanthellae (a type of algae) and the Zooxanthellae provide the polyp with food and gives the coral its recognizable color. Without the Zooxanthellae, coral bleeching occurs.
Zooxanthellae are a type of dinoflagellate that live in the "skin" of hard coral. It's a symbiotic relationship where the zooxanthellae are photosynthetic and produce nutrients for the host coral.
Coral and algae (specifically the algae called zooxanthellae) have an intimate symbiotic relationship. The algae live inside the coral, and provide it with sugars and other photosynthesis byproducts. The coral provides the algae with nutrients for photosynthesis and a safe place to live and reproduce.
one example are whales and barnacles, the barnacle benefits from the whale because it eats and gets protection, and the whale does not seem to be affected in any way.Commensalism is a symbiotic relationship where one party benefits and the other is not harmed. Examples of commensalism in the ocean are barnacles living on turtles, remoras feeding on a shark's food scraps and a crab that makes its home in an oyster's shell.

The eel hides in the coral. The eel eats the animals trying to eat the coral, and gets food and protection from predators. This is called a mutual relationship.
The only one that I am aware of is zooxanthellae, but there may be several species found in corals.
Zooxanthellae. They are tiny plants that make coral.
Almost all coral are predatory, meaning that they capture prey from the water column; this prey is small zooplankton organisms. Some corals also contain a symbiotic algae, called zooxanthellae, that produces sugars and releases some of the sugar to the coral.
Corals capture microscopic particles from plankton floating or swimming past their tentacles. Their nematocysts (organs on their tentacles that can release a whiplike thread sometimes tipped with poisonous spikes) hold and kill their prey. Some corals obtain most of their food by eating zooxanthellae, a type of algae with which the coral have a symbiotic relationship.
