Jacanda was a Thal.
Jacanda went with Temmosus and other Thals to the Dalek City, believing the Daleks would give them food. Instead the Daleks had set an ambush for the Thals, and Jacanda was among those killed. Ganatus told Antodus of Jacanda's death after the surviving Thal scouts returned to their camp. (TV: "The Ambush")
