Quizplus · Accepted Answer

Commensalism is a type of symbiotic relationship in which one species benefits from the association, while the other remains unaffected. The term commensalism is derived from the Latin word com- meaning "together," and mensa, meaning "table," which implies the sharing of resources. The species that benefits from this relationship is called the commensal, while the other is known as the host. In such relationships, the commensal may use the host as a means of transportation, or it may use the host's habitat for shelter or food, without causing any harm to the host. Examples of commensalism include certain species of birds nesting in trees, the remora fish swimming beneath sharks, and barnacles attaching themselves to whales.
