In Mongolia, they prey on argali and rarely Siberian ibex. There are also large populations of the globally endangered argali ("Ovis ammon"). Other ungulate herbivores with overlapping natural ranges include bharal, argali, and goral. Altai argali are the largest of all sheep. Sheep in this ecoregion include the Marco Polo sheep, Tibetan argali, and urial. Argali have been extirpated from northeastern China, southern Siberia, and parts of Mongolia. Also, 56 animal species within the park are considered rare, including argali, dziggetai, Persian gazelle. The attempt to clone argali (mountain sheep) did not produce viable embryos. These sheep are also commonly called "Marco Polo's Argali" or the "Pamir Argali.". Beldeutas has the highest number of argali in the area. While hunting for argali, Kausar fell down a cliff and died. Adult argali eat of food a day. When available, argali readily consume saline soil. Argali reach breeding maturity at two to three years of age.
