Lepisosteidae, commonly known as gar fish, is a family of freshwater and saltwater fish found primarily in North America and parts of Central America. These fish are characterized by their elongated bodies, long snouts filled with sharp teeth, and armored scales. They are known for their ability to breathe air, which allows them to survive in low-oxygen environments. Gars are typically found in slow-moving waters such as rivers, lakes, and swamps. They are carnivorous and primarily feed on smaller fish and invertebrates. The family includes several species, such as the alligator gar and the spotted gar, each adapted to their specific habitats.
