Lake Sturgeon

Acipenser fulvescens

Classification

The lake sturgeon (Huso fulvescens), also known as the rock sturgeon, is a North American temperate freshwater fish, one of 27 species of sturgeon. Like other sturgeons, this species is a bottom feeder and has a partly cartilaginous skeleton, an overall streamlined shape, and skin bearing rows of bony plates on the sides and back. The lake sturgeon uses its elongated, spade-like snout to stir up the substrate and sediments on the beds of rivers and lakes to feed.
