The Pallid Sturgeon is the rarest sturgeon in North America. A dweller in swift, deep, turbid rivers, this ancient, secretive, and elusive fish roams the main channel of the Mississippi and Missouri Rivers, as well as the lower sections of a few large tributaries. There, it uses its vaccuum-tube mouth to suck up the clams, insects, and crustaceans upon which it feeds. Pallid sturgeon are very similar to their smaller cousin, the Shovelnose Sturgeon.
The pallid sturgeon is a critically endangered fish, and as such should not be angled for. Any incidentally caught pallids should be handled carefully and released unharmed.
