The Shovelnose Sturgeon has a unique flat snout that helps it dig in the riverbed for food! These fish can grow quite large and are known for their ancient lineage, dating back millions of years.
Lebensraum: Shovelnose Sturgeons are found in the Mississippi River and its tributaries, preferring sandy or muddy river bottoms.
The Shovelnose Sturgeon has a distinctive flattened, shovel-like snout and a slender body covered in bony plates called scutes, not scales. Its coloration ranges from mottled brown to gray, helping it blend into riverbeds. Four sensory barbels hang in front of its mouth, aiding in bottom foraging.
