There are seven living types of gar fish in the family Lepisosteidae. These ancient-looking predators are recognized by long jaws, sharp teeth, armored diamond-shaped scales, and an air-breathing swim bladder. They occur naturally in North America, Central America, and Cuba, with different species favoring rivers, bayous, wetlands, lakes, reservoirs, and brackish coastal water.
Gar are not pike, despite the old name “garpike,” and they are not the same as marine needlefish sometimes called garfish. This guide focuses only on the seven living true gars.
What Are the Main Types of Gar Fish?
The seven living species are alligator, Cuban, tropical, longnose, shortnose, spotted, and Florida gar. Three belong to Atractosteus, a genus of broad-snouted gars, and four belong to Lepisosteus, which includes the longnose and smaller North American species.
| Species | Scientific name | Best field mark | Native range |
|---|---|---|---|
| Alligator Gar | Atractosteus spatula | Broad, short snout; two rows of large teeth in the upper jaw | Mississippi River basin and Gulf coastal drainages |
| Cuban Gar | Atractosteus tristoechus | Broad snout and heavy body similar to alligator gar | Western Cuba and Isla de la Juventud |
| Tropical Gar | Atractosteus tropicus | Broad snout, gray-green body, irregular dark markings | Southern Mexico and Central America |
| Longnose Gar | Lepisosteus osseus | Extremely long, narrow snout | Broad eastern and central North America |
| Shortnose Gar | Lepisosteus platostomus | Short, broad snout without the alligator gar’s double upper tooth row | Mississippi and Missouri river systems and connected waters |
| Spotted Gar | Lepisosteus oculatus | Numerous dark spots on head, body, and fins | Great Lakes, Mississippi basin, Gulf and Atlantic coastal drainages |
| Florida Gar | Lepisosteus platyrhincus | Broad short snout and irregular dark spots | Florida and parts of nearby Georgia |
1. Alligator Gar
Alligator Gar (Atractosteus spatula) is identified most quickly by broad, short snout; two rows of large teeth in the upper jaw. Its native range includes mississippi river basin and gulf coastal drainages, where it uses fresh water, large rivers, bayous, reservoirs, and brackish coastal areas.
The largest living gar and a powerful apex predator. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
2. Cuban Gar
Cuban Gar (Atractosteus tristoechus) is identified most quickly by broad snout and heavy body similar to alligator gar. Its native range includes western cuba and isla de la juventud, where it uses freshwater rivers, lakes, wetlands, and occasional brackish areas.
A geographically restricted species with important conservation value. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
3. Tropical Gar
Tropical Gar (Atractosteus tropicus) is identified most quickly by broad snout, gray-green body, irregular dark markings. Its native range includes southern mexico and central america, where it uses warm lowland rivers, floodplains, lakes, and wetlands.
Important in regional fisheries and aquaculture. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
4. Longnose Gar
Longnose Gar (Lepisosteus osseus) is identified most quickly by extremely long, narrow snout. Its native range includes broad eastern and central north america, where it uses rivers, lakes, reservoirs, estuaries, and coastal waters.
One of the most widespread gars and easily recognized by its beak-like jaws. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
5. Shortnose Gar
Shortnose Gar (Lepisosteus platostomus) is identified most quickly by short, broad snout without the alligator gar’s double upper tooth row. Its native range includes mississippi and missouri river systems and connected waters, where it uses large rivers, backwaters, oxbows, and reservoirs.
Usually smaller and less heavily spotted than spotted gar. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
6. Spotted Gar
Spotted Gar (Lepisosteus oculatus) is identified most quickly by numerous dark spots on head, body, and fins. Its native range includes great lakes, mississippi basin, gulf and atlantic coastal drainages, where it uses vegetated lakes, bayous, swamps, and slow rivers.
Prefers clear, shallow, plant-rich habitats. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
7. Florida Gar
Florida Gar (Lepisosteus platyrhincus) is identified most quickly by broad short snout and irregular dark spots. Its native range includes florida and parts of nearby georgia, where it uses canals, lakes, ponds, swamps, and slow rivers.
Often confused with spotted gar but has a more restricted southeastern range. Like other gars, it can gulp air at the surface, an adaptation that helps it survive in warm or oxygen-poor water. It usually waits or cruises slowly before striking prey with a rapid sideways sweep of the head.
Anglers should use strong tackle, long pliers, and careful handling because the jaws contain sharp teeth and the ganoid scales are hard. Regulations and conservation status vary, so always confirm local rules before targeting or keeping gar.
How Are These Types of Fish Classified?
| Genus | Living species | General pattern |
|---|---|---|
| Atractosteus | Alligator, Cuban, tropical gar | Broad-snouted, heavy-bodied gars; alligator gar has two rows of large upper-jaw teeth. |
| Lepisosteus | Longnose, shortnose, spotted, Florida gar | Includes the extremely long-snouted longnose gar and several smaller, spotted or short-snouted species. |
Where Do These Fish Live?
Gars use slow rivers, large river channels, oxbows, swamps, backwaters, reservoirs, lakes, canals, floodplains, and brackish estuaries. They often favor warm shallow areas with vegetation or woody cover, although large alligator gar also use major river systems. Surface access is essential because gars regularly breathe air.
How to Identify Different Types of Gar Fish
- Snout length: longnose gar has the narrowest, longest snout; shortnose and Florida gar have much shorter jaws.
- Tooth rows: adult alligator gar has two rows of large teeth in the upper jaw.
- Spots: spotted gar usually has abundant spots on the head, body, and fins; shortnose gar is less heavily marked.
- Range: Cuban and tropical gars have restricted southern distributions, while longnose gar is widespread.
- Body size: alligator gar becomes much larger and heavier-bodied than spotted, Florida, or shortnose gar.
- Use a local key: juvenile gars can be difficult to separate by photographs alone.
Fishing Tips and Notes
- Use tackle matched to powerful fish and abrasive mouths.
- Employ a leader appropriate for local techniques and regulations.
- Wait for a secure hook placement rather than striking wildly at the first movement.
- Use a large knotless landing net or safe boat-side release method.
- Keep hands away from the jaws and use long-handled tools.
- Support the body horizontally and minimize air exposure.
- Report tagged fish or notable catches when local agencies request data.
Safety, Sustainability, and Conservation Notes
Gar eggs are toxic and must not be eaten. Gar flesh is eaten in some regions, but cleaning requires care because of the hard scales. Populations, legal status, harvest seasons, and size limits differ widely. Large mature gars can be long-lived and valuable breeders, so selective harvest and careful release are important. Never move live gar between waters or release aquarium specimens.
Fun Facts About Gar Fish

Final Thoughts on Types of Gar Fish
The seven living types of gar fish can be separated by snout shape, tooth rows, spotting, size, and native range. Alligator gar is the giant broad-snouted species; longnose gar has the longest jaws; spotted and Florida gar are heavily patterned; shortnose gar has a compact snout; and Cuban and tropical gar have restricted southern ranges. Respect their teeth, protect large breeding fish, and follow local laws.
