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.
The term host is used for the larger of the two members of a symbiosis.
Symbiosis may be divided into two distinct categories: ectosymbiosis and endosymbiosis.
In ectosymbiosis, the symbiont lives on the body surface of the host, including the inner surface of the digestive tract or the ducts of exocrine glands.
