The alligator gar (Atractosteus spatula) is a large, primitive freshwater fish found in North America. It is the largest species in the gar family (Lepisosteidae) and one of the largest freshwater fishes in North America, capable of reaching lengths of over 10 feet (3 meters) and weighing several hundred pounds.
The name “alligator gar” comes from its long, broad snout, which resembles that of an alligator. This species has a dark olive or brownish coloration with irregular blotches or spots along its body, providing effective camouflage in its habitat. Alligator gars have a dual row of sharp teeth in their long jaws, which they use to capture prey such as fish, waterfowl, and small mammals.
Alligator gars are primarily found in slow-moving or stagnant waters, including rivers, lakes, bayous, and swamps, throughout the southern United States, from the Gulf Coast states to the Mississippi River basin. They are ambush predators, often lying in wait among submerged vegetation or near the water’s surface for unsuspecting prey to pass by.
These fish have faced habitat loss, pollution, and overfishing pressures in some areas, leading to declines in their populations. However, there are conservation efforts underway to protect and restore their habitats and populations. Alligator gars are also valued by some anglers for their challenging sport fishing opportunities, although regulations may be in place to manage their harvest.
