Lake Sturgeon have scales but not the cycloid scales associated with most bony fishes, rather they are covered by the much stronger ganoid scales. The tail upper lobe is much larger than the rounded lower lobe. Lake Sturgeon have a single dorsal fin located far back near the caudal (tail) fin.
The barbels are sensory organs that assist the sturgeon in finding prey on the river and lake bottoms. Lake Sturgeon have a large protrusible, suctorial mouth on the bottom side of the head with four barbels in front of the mouth and beneath the snout. (Native Fish) A notable characteristic is the five rows of bony plates (scutes) that are well developed in young fish but less distinguishable in adults.
