The Lake Sturgeon or Acipenser fulvescens is a massive freshwater fish. It is a bottom feeder that eats insect larvae, worms, crayfish, snails, and other small fishes. As you can see above, they have a very unique mouth which they use like a vacuum for feeding. The Lake Sturgeon averages about 200 to 300lbs, but they have been reported to be over 800lbs and over 8' long! This Sturgeon doesn't have any scales, it is instead covered with five rows of bone like plates on its back sides and stomach. This dinosaur of fish can reach over 150 years old, no wonder it gets so big! They are found only in North American in states like Michigan and Wisconsin. There are over 20 different species of Sturgeon in the world, but this one like many others is protected in most places.
