After the Beceite ibex, the Gredos ibex is the largest and darkest in color and has the largest horns. Typically, the horns are lyre-shaped with a pronounced curve and a spiral turn of more than 180 degrees. Horn thickness decreases progressively from the base to the very thin tip. While this is the typical Gredos horn conformation, other horn shapes may be found in this region and even in the same herd.
