The Alligator Gar (Atractosteus spatula) is a large, primarily freshwater fish native to North America. It is distinguished by its broad snout and dual rows of sharp teeth, resembling an alligator, which contribute to its name. As an ambush predator, it primarily feeds on fish but may also consume waterfowl and small mammals. The species is notable for its ability to breathe both air and water, allowing it to inhabit oxygen-poor environments.
