About
The white sturgeon is North America's largest freshwater fish, reaching lengths that easily rival a standard sofa.
The white sturgeon is the largest freshwater fish species in North America, with rare historic records describing specimens over double this size. Females grow significantly larger and live longer than males, sometimes living for over a century. Instead of typical fish scales, their bodies are lined with rows of thick bony plates called scutes that add substantial bulk.
