Acipenser oxyrinchus oxyrinchus, known as the Atlantic sturgeon, inhabits the western Atlantic Ocean and coastal rivers from Canada to Florida. These prehistoric fish are notable for their bony armor plates, elongated bodies, and ability to grow over 14 feet long. They are anadromous, migrating from saltwater to freshwater to spawn.

Acipenser oxyrinchus oxyrinchus, commonly known as the Atlantic sturgeon, is native to the Eastern coast of North America. Its range extends from the St. Lawrence River in Canada through the eastern United States down to the St. Johns River in Florida.

Atlantic sturgeons are anadromous fish, meaning they migrate from saltwater to freshwater to spawn. They typically inhabit estuarine and coastal waters, preferring large rivers and bays with sandy or muddy substrates. The species thrives in a variety of salinity levels but is often found in brackish water during its lifecycle. The water temperature during spawning generally ranges from 13°C to 20°C (55°F to 68°F).

The Atlantic sturgeon occupies a niche as a bottom-dwelling fish that feeds primarily on benthic invertebrates. It plays a significant role in the ecosystem by contributing to the benthic community's dynamics and serving as prey for larger marine predators during its early life stages. This species is known for its long migrations, which allow it to exploit different habitats at various life stages, from freshwater rivers for spawning to coastal marine environments for growth and maturation.
