By 2262 at least two Yolu had begun training as Anla'shok. The Yolu are bipedal humanoids in appearance and feature high foreheads, short triangular noses with elongated nostrils, ears and a distinctive "gap" that runs from the center of the forehead to the bridge of the nose.Like humans, Yolu are four limbed bipeds and have five digits on their hands, though their feet have no toes. Yolu skin is similar to that of humans in texture and its color varies from light yellow to black. The Yolu can perceive a much wider visible spectrum than humans and can see very well in the dark.
