Some religions declare certain animals to be sacred, and in modern times concern for the natural environment has provoked activists to protest...

Species  -  Latest posts  /  Genres  -  Latest posts  /  Animals  -  Latest posts  /  Mammals Saiga antelope The saiga antelope, (Saiga tatarica) is a critically endangered antelope that originally inhabited a vast area of the Eurasian steppe zone from the foothills of the Carpathian Mountains and Caucasus into Dzungaria and Mongolia. They also lived in Beringian North America during the Pleistocene. Today, the dominant subspecies (S. t. tatarica) is only found in one location in Russia (in the Republic of Kalmykia and Astrakhan Oblast) and three areas in Kazakhstan (the Ural, Ustiurt, and Betpak-Dala populations). A proportion of the Ustiurt population migrates south to Uzbekistan and occasionally Turkmenistan in winter. It is extinct in China and southwestern Mongolia. It was hunted extensively in Romania and Moldova until it became extinct in those regions at the end of the 18th century. The Mongolian subspecies (S. t. mongo...
