What is the siberian sturgeon?
The Siberian sturgeon (Huso baerii) is a species of sturgeon in the family Acipenseridae. It is most present in all of the major Siberian river basins that drain northward into the Kara, Laptev and East Siberian Seas, including the Ob, Yenisei (which drains Lake Baikal via the Angara River) Lena, and Kolyma Rivers. It was also found in Kazakhstan and China in the Irtysh River, a major tributary of the Ob, though wild populations are extirpated in China. The species epithet honors the German Russian biologist Karl Ernst von Baer.
