Ectosymbiosis is symbiosis in which the symbiont lives on the body surface of the host, including internal surfaces such as the lining of the digestive tube and the ducts of glands. An example of an ectosymbiote are the iron-oxide associated bacteria found crusted to the gills of Rimicaris exoculata shrimp.[1]
