The nomads of the ocean, Kawésqar and Yagáns people, physically were short, long arms and strong people. Their legs, however, were shorter and weaker.
The bodies of these Fueguian canoeists had adapted to the hunting and harvesting of marine products.
Their main activities, rowing, hunting, or diving, required greater strength in the arms and torso than in the legs.
As an average, men measured 1,60 meters and women, 1,47 meters.
Their height was one of the main differences with the Patagonian hunters: the Aonikenk (Tewelches) and Selk'nam (Onas) people could be up to two meters high.
