The Saiga antelope is a critically endangered antelope that once inhabited a vast area of the Eurasian steppe. This unusual antelope has a distinctive pair of closely spaced, bloated nostrils directed downward. The coat of these animals changes according to the season. Today, Saigas are only found in one region in Russia (in the Republic of Kalmykia and Astrakhan Oblast) and three areas in Kazakhstan (the Ural, Ustiurt, and Betpak-Dala populations). A portion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. These rare antelopes live in semideserts, steppes, grasslands, and possibly open woodlands where they may shelter during strong winds.
