Parts of the beluga sturgeon can be served as food, and the texture is often compared to that of a lobster or crab. The life span of a male sturgeon is 55 years and 80 to 150 years for females. Beluga sturgeons impose no threat to humans, in fact, they actively avoid contact with humans. Beluga sturgeons eat flounder, anchovies, gobies, herring, roach, and other fishes as food.
