The Alligator Sturgeon, also known as the crocodile sturgeon, is a species of sturgeon native only to the Great Lakes. It is named because of their longer and strong jaws than the Atlantic sturgeon, and is also aggressive to other native fish and even to nonnative fish species, there have also been reports of alligator sturgeons attacking people and rarely killing people due to their aggressive nature. They might be the natural predators of most native fish of the Great Lakes, but their populations are declining due to competition for food and predatation by invasive whales. People are trying to save this fish species from extinction by using genetic engineering to help make this fish tolerate nonnative fish and mammals, and people are also trying to preserve this fish species by culling some whales out of the Great Lakes.
