Gulf sturgeon jumping on the Suwannee River, Florida. Large jumping sturgeons can inflict serious injuries to humans who get in the way.

The Gulf sturgeon (Acipenser oxyrinchus desotoi) is a subspecies of sturgeon that lives in the Gulf of Mexico and some rivers draining into it. The Gulf sturgeon was first recognized as a separate subspecies in 1955. The nominate subspecies is the Atlantic sturgeon, A. o. oxyrinchus.[5] The Gulf sturgeon is listed as threatened under the United States Endangered Species Act, having been listed in 1991.[2][3] Critical habitat, reflecting the range of the subspecies deemed essential for its continued survival, has been designated (see map).[6] The historical range is thought to have been from the Suwannee River on the western coast of Florida to the Mississippi River, and marine waters of the central and eastern portions of the Gulf of Mexico. Three sturgeon species in genus Scaphirhynchus share river territory with the Gulf sturgeon; none of the other sturgeon species is anadromous.[7]
