The longnose gar, Lepisosteus osseus, is a primitive ray-finned fish of the gar family. It is also known as the needlenose gar. L. osseus is found along the east coast of North and Central America in freshwater lakes and as far west as Kansas and Texas and southern New Mexico. The gar have been present in North America for about 100 million years. Predation is not a problem on adult longnose gar, but they are vulnerable to other gar predation when they are young, including adult longnose gar. Their declining populations are due to overfishing, habitat loss, dams, road construction, pollution, and other human-caused destruction of the aquatic systems. Overfishing is more of a trophy fish than for food; people find their meat to have a mild but tasty flavor. Currently, longnose gar are found in Central America, Cuba, North America, and the Isles of Pines. Longnose gar are frequently found in fresh water in the eastern half of the United States, but some gar were found in salinities up to 31 ppt. Their microhabitats consist of areas near downed trees, stone outcrops, and vegetation. The decline of their population is mainly due to human manipulation of aquatic systems.
