Trill (Star Trek)

The Trill are a fictional species of symbiotic life forms, depicted in the Star Trek media franchise. First introduced in an episode of Star Trek: The Next Generation, the species became a major part of the spin-off series, Star Trek: Deep Space Nine, which featured a Trill named Dax as one of its main characters.

Trill are depicted as comprising a humanoid host, and a worm-shaped symbiont that is implanted in the host's abdomen. Their personalities are a combination of the host and symbiont, with the symbiont's memories providing continuity between hosts. Their home world, also named Trill, is a planet in the Alpha Quadrant, the primary setting of most of the Star Trek series.
