Shovelnose Sturgeon vs White Sturgeon
A shovelnose sturgeon and a white sturgeon share the same ancient armoured body plan and bottom-feeding lifestyle, but the two sit at almost opposite ends of the size spectrum among North American sturgeon species.
| Shovelnose Sturgeon | White Sturgeon | |
|---|---|---|
| Scientific name | Scaphirhynchus platorynchus | Acipenser transmontanus |
| Relative size | Smallest North American sturgeon | One of the largest freshwater fish in North America |
| Snout shape | Flattened, shovel-shaped | More elongated, less flattened |
| Native range | Mississippi and Missouri River systems | Pacific coast rivers of North America |
| Habitat | Wetlands and rivers | Wetlands and coastal rivers |
| Feeding method | Sediment-stirring, barbel-assisted | Bottom feeding, barbel-assisted |
| Body armour | Rows of bony scutes | Rows of bony scutes |
| Conservation status | Least Concern | Least Concern |
Shovelnose Sturgeon vs White Sturgeon: common questions
How much bigger is the white sturgeon than the shovelnose sturgeon?
The white sturgeon is dramatically larger, ranking among the largest freshwater fish found anywhere in North America, while the shovelnose sturgeon is the smallest sturgeon species native to the continent, making the size difference between these two sturgeon relatives one of the most extreme within the entire family.
Do both sturgeon species feed the same way?
Both species are bottom feeders that use sensitive barbels to detect prey, though the shovelnose sturgeon relies specifically on its flattened, shovel-shaped snout to actively stir up river-bottom sediment and expose hidden invertebrates, a more specialised feeding technique than the white sturgeon typically uses.
Where does each sturgeon species live?
The shovelnose sturgeon is native to the Mississippi and Missouri River systems across the central United States, while the white sturgeon is found along Pacific coast rivers of North America, meaning the two species occupy largely separate river systems on opposite sides of the continent.
