Commensalism is a type of symbiotic relationship between two organisms where one benefits while the other is neither helped nor harmed. An example of commensalism is the relationship between barnacles and whales.
Barnacles attach themselves to the skin of whales and benefit by being carried to different feeding areas, which helps them access more food. The whale, on the other hand, is not significantly affected by the presence of the barnacles. This relationship illustrates how one species can gain from another without impacting it negatively.
