Sturgeon are large, primative looking fish.
The mouth is protractile and is located underneath a pointed snout. Four barbels line the front of the mouth. Five rows of scutes extend the length of the body- one on the back, one on each side, and two on the belly. Atlantic sturgeon are either dark brown or olive green, and may be distinguished from the shortnose sturgeon by their much longer snouts. Body elongate, heavy-set when mature, somewhat cylindrical.
