Thals looked much like Kaleds and humans, though they could be distinguished from Kaleds by their blond hair and light eyes. (TV: The Daleks, Planet of the Daleks, Genesis of the Daleks) Internally, Thals could also be distinguished from humans and Kaleds. They had thinner and longer lungs than the Kaleds (AUDIO: Corruption) and greater resistance to radiation. (TV: The Daleks) The name of the Thal state was the Thal Republic. (AUDIO: Corruption)
