Commensalism is a form of symbiotic relationship. It is a relationship between different species where one organism gains benefit from the relationship and the other is unaffected.
A good example of a commensalism is that of smaller organisms 'hitching' a lift on larger organisms (this is known as Phoresy). The smaller organism derives benefit from the other organism and the larger organism is unaffected.
