Florida Gar

The Florida Gar (Lepisosteus platyrhincus) is a member of the ancient gar family Lepisosteidae, endemic to the Florida peninsula and adjacent parts of southern Georgia in the southeastern United States. It occupies rivers, lakes, springs, and canals throughout its limited range, thriving in the warm, clear-to-tannic waters typical of Florida's freshwater systems. As with other gars, it retains primitive features including hard ganoid scales and an air-breathing swim bladder. The species remains common and is not considered at risk, well adapted to the diverse freshwater habitats of its native peninsula.

Florida Gar can be told apart from other gars by the following traits:

• Elongated cylindrical body densely covered in dark round spots, including on the head
• Spotting extends onto all fins, more extensively than in the similar Spotted Gar
• Moderately long, slender snout lined with sharp teeth
• Olive-brown dorsal coloring fading to a lighter, heavily marked belly and flanks
• Rounded caudal fin

Its geographic range is the clearest clue, as it is essentially restricted to the Florida peninsula, where it overlaps very little with other gar species.

This species is restricted to freshwater habitats of the Florida peninsula and extreme southern Georgia, including rivers, natural springs, lakes, marshes, and canals. It favors clear to tannin-stained, vegetated waters and tolerates a wide range of conditions from spring-fed streams to slow blackwater rivers. Like other gars, an air-breathing swim bladder allows it to survive in warm, oxygen-poor waters common in Florida's shallow lakes and wetlands during the hottest months. It is exclusively a freshwater species, rarely if ever entering brackish water.

Florida Gar are solitary ambush predators that hover near submerged vegetation or structure, striking sideways at small fish and invertebrates with a rapid snap of the jaws. They frequently surface to gulp air, a behavior especially important in Florida's warm, often low-oxygen waters. Spawning occurs in spring, when adults move into shallow, vegetated areas to scatter adhesive eggs, which are left unguarded and hatch within about a week. Juveniles remain hidden among plants, relying on camouflage until they grow large enough to become active predators themselves.
