*The Trill are a joined species comprised of two distinct life-forms which live in a symbiotic state. There is a humanoid species which serves as a host body, and an androgynous, invertebrate symbiont, which lives interdependantly within the host. The symbiont lives much longer that the host body and will normally be transfered to a number of hosts throughout its lifetime, carrying the cumulative experience with it. *Source: Back of card
