Jadzia Dax is a joined Trill. Though she appears to be a young woman, Jadzia lives in symbiosis with a long-lived creature, known as a symbiot, named Dax; Jadzia is Dax's eighth host. The two share a single, conscious mind, and her personality is a blending of the characteristics of both the host and the symbiont. As such, Jadzia has access to all the skills and memories of the symbiont's seven previous hosts. Prior to the symbiotic joining, Jadzia earned academic degrees in exobiology, zoology, astrophysics, and exoarchaeology.
