Description

The shovelnose sturgeon is a sturgeon (Acipenseridae) from central North America. The species grows to about 1 metre and has an elongate body with rows of bony plates, a flattened, shovel-shaped snout and four barbels before the inferior sucker mouth. It inhabits the bottom of the main channels and embayments of large, turbid rivers, often in flowing water over sand mixed with gravel and mud. With its barbels and sucker mouth it searches the bottom for insect larvae and other invertebrates. Owing to dams and habitat loss the species is considered vulnerable. It is harmless to humans.
