Alabama Sturgeon

The Alabama Sturgeon is a brackish-water fish classified within the family Acipenseridae, one of the oldest extant fish families on Earth. Known scientifically as <em>Scaphirhynchus suttkusi</em>, this sturgeon is among the rarest freshwater fishes in North America. It inhabits the Mobile River basin of Alabama, historically ranging through the main channel and larger tributaries. Sturgeon of the genus Scaphirhynchus are characterized by their shovel-shaped snouts, bony scutes along their bodies, and bottom-feeding behavior, using sensitive barbels to locate invertebrates and small organisms in sandy or gravel river beds. The Alabama Sturgeon is highly adapted to large, free-flowing river systems with strong currents, deep pools, and coarse substrates. Commercial navigation projects, water quality degradation, and altered flow regimes have severely curtailed its population. Specific size records for this species are not well documented, reflecting both its rarity and the difficulty of studying wild individuals. Taxonomically distinct from the related Shovelnose Sturgeon, <em>Scaphirhynchus suttkusi</em> represents a unique evolutionary lineage within North American ichthyofauna. Ongoing conservation and monitoring efforts aim to better understand its ecology and support potential recovery measures across its highly restricted range.
