Teal'c's symbiote. From the Stargate SG-1 Season 1 episode, The Enemy Within. The term symbiote (or symbiont) refers to a Goa'uld parasite living in a host animal such as a human or Unas. In biology a symbiote is an organism that lives with or off another organism receiving and/or giving benefits.
The third main type of symbiosis is parasitism. This is when one species benefits from the interaction and the other species is harmed. A parasite is an organism that lives on or within a host species. The host provides food and shelter to the parasite, but at a cost to the host itself.
