Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [1] This is in contrast with mutualism , in which both organisms benefit from each other; amensalism , where one is harmed while the other is unaffected; and parasitism , where one is ...
Commensalism benefits one organism and the other organism is neither benefited nor harmed. It occurs when one organism takes benefits by interacting with another organism by which the host organism is not affected. A good example is a remora living with a manatee. Remoras feed on the manatee's faeces.
For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food. The whale is not harmed, but it also does not receive any benefits so this is also an example of commensalism. An example of ectosymbiotic bacteria is cutibacterium acnes. These bacteria ...
An additional ectosymbiotic example of commensalism is the relationship between small sessile organisms and echinoids in the Southern ocean, where the echinoids provide substrate for the small organisms to grow and the echinoids remain unaffected. [8] Branchiobdellid annelids are mutualistic parasites.
An example of such "whole-community" facilitation is substrate stabilization of cobble beach plant communities in Rhode Island, US, by smooth cordgrass (Spartina alterniflora). [6] Large beds of cordgrass buffer wave action, thus allowing the establishment and persistence of a community of less disturbance-tolerant annual and perennial plants ...

There are three types of host-pathogen interactions based on how the pathogen interacts with the host. Commensalism is when the pathogen benefits while the host gains nothing from the interaction. An example of this is Bacteroides thetaiotaomicron, which resides in the human intestinal tract but provides no known benefits. [6]
