The Trill were a humanoid species native of the planet Trill, recognizable by the spots running down the sides of their heads and bodies. Some humanoid Trill lived with a Trill symbiont within them. Their species was a member of the United Federation of Planets. (Star Trek: The Next Generation; Star Trek: Deep Space Nine; Star Trek: The Cantabrian Expeditions)
Isoboramine regulated connections between the symbiont and the host in joined Trills, and this neurotransmiter needed to remain within tolerable ranges. If the level fell below 40%, the host and the symbiont were at risk of death. (Star Trek: Deep Space Nine)
The Trill Symbiosis Commission bore responsibility for matching symbionts to hosts. Approximately 300 symbiont were available annually to join with one of 5,000 potential hosts. (Star Trek: Deep Space Nine)
The symbiont remained the host's top priority, and the host would give his or her life to protect the symbiont from harm or death. In 2372, a fatally-wounded Ulitania Jonar requested Dr. Marie Bourget remove the Jonar symbiont and transfer it to Tawana Killan to save the symbiont. (Star Trek: The Cantabrian Expeditions: "Oh, What a Lovely War")
