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

anadromous.[7]

Physical appearance

Visually, Gulf sturgeon are almost impossible to differentiate from Atlantic sturgeon, as the most significant morphological difference is the

grass shrimp, marine worms, isopods, and amphipods, their unique feeding pattern possibly reflects an adaptation to prevent PSP that coincides with higher rates of algal blooms in summer.[5][7]

Life cycle

Juvenile Gulf sturgeon remain in the spawning river until roughly two years of age, eating there. Thereafter, they join the adults in their anadromous

spring on the river bottom feeding groundwater into the river. After spawning, the adults and older juveniles collect in regions of cooler, deeper, slower-flowing water, generally downstream of springs.[5] [8][7]

Jumping

All species of sturgeon leap out of the water at times. The Gulf sturgeon tends to jump during July and August, and again early during the offshore feeding period. They are thought to jump to communicate and maintain group cohesion.[8] Due to their heavy body armor, large leaping sturgeon can inflict serious injuries to humans who are in the way.[9] On July 2, 2015, a leaping sturgeon on the Suwannee River in Florida struck and killed a 5-year-old girl.[10]

Population controls

glochidia (larvae) of three freshwater mussel species. Overfishing and dam construction probably contributed to the historical decline in populations.[7]
