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. Four sensory organs hang near its mouth to help the sturgeon locate bottom-dwelling prey. Lake sturgeons can grow to a large size for freshwater fish, topping 7.25 ft (2.2 m) long and 240 lb (108 kg). [8]
Lake shorelines are fractal. [7] This means that measurements of shore length are longer when measured on high-resolution maps compared to low-resolution maps. [9] [10] Therefore, a lake's shoreline development index will be greater when calculated based on shorelines measured from high-resolution maps compared to low-resolution maps. [10]
The description lacks information on length, girth and mass. Later in the article there is a mention of the mass of one individual. Aren't figures available for median and maximum recorded values?

The sturgeon which spawn annually in the springtime in the Wolf River and its parent, the Fox River, between approximately April 15 and May 5, as they swim upstream from Lake Winnebago.
