Lepisosteus osseus, commonly known as the Longnose Gar, is a freshwater fish known for its elongated, torpedo-shaped body and long, narrow snout filled with sharp teeth. It inhabits slow-moving rivers and lakes in North America and exhibits unique ambush predatory behavior, often floating motionless near the surface to catch unsuspecting prey.

Lepisosteus osseus, commonly known as the longnose gar, is native to North America. Its geographical distribution includes the eastern United States, southern Canada, and northern Mexico. Specifically, it is found in the Mississippi River basin, the Great Lakes region, and along the Atlantic and Gulf Coasts.

Longnose gars inhabit freshwater environments, typically in slow-moving rivers, lakes, and reservoirs. They prefer clear and brackish waters with abundant vegetation, which provides cover and breeding grounds. The species is adaptable and can also tolerate low oxygen levels and varying salinities, allowing it to survive in estuarine conditions as well.

As a top predator in its habitat, the longnose gar plays a crucial role in controlling fish populations, primarily feeding on smaller fish and occasionally crustaceans. Its elongated body and long snout with sharp teeth are adapted for ambush predation, allowing it to swiftly capture prey in vegetated or open water environments.
