This gar fish species identification guide is made just for kids who love learning about cool fish! Gars are ancient-looking freshwater fish with long snouts and sharp teeth. This list will help you spot and name 10 different types of gar fish, showing what makes each one special and easy to recognize.
Longnose Gar (Lepisosteus osseus)
The Longnose Gar is one of the most common gars found in North America. It has a very long, thin snout filled with sharp teeth, which it uses to catch smaller fish. Its body is covered with diamond-shaped scales that are hard and look like armor. These gars can grow up to 6 feet long, making them one of the biggest gars kids might hear about.
Spotted Gar (Lepisosteus oculatus)
The Spotted Gar gets its name from the many black spots that cover its body and fins. It has a shorter snout compared to the Longnose Gar but still has the same tough, armored scales. This gar lives mostly in slow-moving rivers and swamps in the southern United States. Its spots help it blend in with plants and shadows underwater.
Shortnose Gar (Lepisosteus platostomus)
The Shortnose Gar has a much shorter and wider snout than most gars, which makes it easy to tell apart. It has fewer spots on its body and usually grows up to 3 feet long. This gar prefers clear, calm waters like lakes and slow rivers. Its blunt snout helps it crush prey like crayfish and small fish.
Alligator Gar (Atractosteus spatula)
Named because its snout looks like an alligator’s mouth, the Alligator Gar is the largest gar species. It can grow over 10 feet long and weigh more than 300 pounds! This giant is found in the southern U.S. and Mexico, often in big rivers and lakes. Its broad snout is filled with many sharp teeth, and it can live in both fresh and brackish water.
Florida Gar (Lepisosteus platyrhincus)
The Florida Gar has a short, wide snout like the Shortnose Gar but is smaller, usually around 2 feet long. It has fewer spots but a distinctive black mark near each eye. This gar is mostly found in Florida’s freshwater lakes and slow rivers. Its broad snout helps it catch small fish hiding in plants.
Eyetail Spotted Gar (Lepisosteus oculatus ssp.)
The Eyetail Spotted Gar is a subspecies of the Spotted Gar and is named for the dark spot at the base of its tail fin, which looks like an eye. Its body is covered in small black spots, and it has a long snout. This gar lives in the southern United States and is great at hiding in thick vegetation because of its spotted pattern.
Black Gar (Atractosteus tristoechus)
The Black Gar is a rare species found mainly in Cuba and parts of Central America. It has a dark, almost black body with fewer spots than other gars. Its snout is broad and strong, like the Alligator Gar but smaller. This gar is special because it lives mostly in slow, swampy waters and is less well-known than other gars.
Spotted Longnose Gar (Lepisosteus oculatus longirostris)
This species is a variation of the Spotted Gar with an even longer snout. It has the classic black spots but uses its long nose to reach into tight spaces to catch prey. It’s found mostly in the southeastern U.S. and prefers clear streams and rivers. Kids can spot it by its long, toothy snout and dotted body.
Florida Longnose Gar (Lepisosteus platyrhincus longirostris)
The Florida Longnose Gar is similar to the Florida Gar but with a longer snout. It’s smaller than the Longnose Gar but has a snout that helps it catch small fish in Florida’s freshwater systems. Its body is less spotted, and it’s often found in weedy areas where it hides from predators.
Western Gar (Lepisosteus occidentalis)
The Western Gar is found in parts of Mexico and the southwestern U.S. It has a medium-length snout and a body covered with diamond-shaped scales. Unlike the spotted gars, the Western Gar has fewer spots and a more uniform color, usually olive or brown. It lives in warm rivers and lakes and is known for being very strong and fast.
How to Choose
When trying to identify a gar, look closely at the shape and length of its snout—this is one of the easiest ways to tell species apart. Next, check for spots on the body and fins, as some gars have many spots while others have few or none. Size can also help; for example, the Alligator Gar is huge compared to others. Lastly, think about where the gar lives—different species prefer different types of water like lakes, slow rivers, or swamps. Using these clues will help you pick which gar you’re looking at!
