metabiosis is a more indirect dependency, in which one organism creates or prepares a suitable environment for a second. examples include maggots, which feast and develop on corpses, and hermit crabs, which use gastropod shells to protect their bodies.

an epibiont (from the ancient greek meaning "living on top of") is an organism that lives on the surface of another living organism. an epibiont is, by definition, harmless to its host. in this sense, the interaction between the two organisms can be considered neutralistic or commensalistic; as opposed to being, for example, parasitic, in which case one organism benefits at the expense of the other, or mutualistic, in which both organisms obtain some explicit benefit from their coexistence). examples of common epibionts are barnacles, remoras, and algae, many of which live on the surfaces of larger marine organisms such as whales, sharks, sea turtles, and mangrove trees. the host of the epibiont is typically referred to as the basibiont ("living underneath").
