Young longnose gar grow rapidly and studies have shown that they can gain 3.2 mm and 1.8 grams per day, when maintained in aquaria with an unlimited food supply (Riggs and Moore, 1960). osseus larvae (sac-fry) are relatively inactive and possess an adhesive structure at the tip of the snout by which they attach to objects in the water. The yolk sac is absorbed at approximately 12 mm TL and fins form around 30 mm TL (Simon and Wallus, 1989). osseus eggs typically hatch 3-9 days after they have been laid and the larvae are approximately 8-10 mm long at hatching (Yeager and Bryant, 1983 Becker, 1983). The dorsal and anal fins of the longnose gar are located far back on the body, which is encased in a heavy armor of interlocking, rhomboid, ganoid scales (Ross, 2001). osseus have a narrow brown stripe along their back and a broad dark brown strip along their sides (Page and Burr, 1991 Becker, 1983). Dark spots can be found on the median fins and, in individuals from clear water, on the body. osseus are olive brown in color with a white belly. Longnose gar have long, narrow snouts more than twice as long as the rest of the head and they have abundant, sharp, villiform teeth. osseus can tolerate high water temperatures and can often be found near the water surface on warm days or nights (Becker, 1983).
They can live in brackish water and are common in the deeper bayous along the Gulf Coast (Goodyear, 1967).
osseus live in a variety of lowland habitats, preferring sluggish areas of larger rivers, lakes, reservoirs and estuaries. It lives throughout the entire Mississippi River basin and can be found as far south as the Rio Grande drainages of Texas and Mexico (Page and Burr, 1991). Lawrence River, Quebec and all of the Great Lakes except Superior. to central Florida and in the upper Midwest in the St. osseus can be found along the eastern seaboard from the Delaware River, N.J. Lepisosteus osseus is widely distributed throughout the eastern United States.
