Исчезающие виды России. Антилопа сайга Сайга живет в степях северо западного прикаспийского района России. Она имеет более длинный нос чем другие антилопы. Она может быстро бегать и может также хорошо плавать. Сайга живет в открытых пространствах. Она путешествует(перемещается) с место на место большими группами. Сайга ест траву и другие растения. Число антилоп падает потому что люди охотятся за их рогами. Сегодня популяция сайги только 1500 и каждый год их число становится меньше.
