The lake sturgeon uses its long snout to move the dirt on the floor of rivers and lakes to eat. Four organs (barbels) are near its mouth to help the sturgeon find ground-based prey. Lake sturgeons can grow to a large size for freshwater fish, getting up to 7.25 ft (2.2 m) long and 240 lb (108 kg).[5]
