In commensalism, one member of the association benefits and the other is neither helped nor harmed. Small marine animals called barnacles, for example, often attach themselves to a whale's skin. The barnacles perform no known service to the whale, nor do they harm it. Yet, the barnacles benefit from the constant movement of water past the swimming whale, because the water carries food particles to them.
