Did you know that there are over seven different types of gar fish out there? While they differ in appearance and location, all of them have hard scales and jaws that are full of sharp teeth.
These fish are related to the bowfin and live in freshwater habitats. However, some can be found in saltwater too.
Before you go gar
These ancient predators, belonging to the family Lepisosteidae (often called garpike), primarily inhabit freshwater ecosystems across North America, though some species tolerate or even thrive in brackish or saltwater environments. A unique adaptation is their vascularized swim bladder, which functions like a primitive lung, allowing them to gulp air and survive in low oxygen levels common in backwaters and bayous.

A Look at Common Gar Species
There are seven recognized living species of gar. Let’s explore some of the most well-known:
- Longnose Gar
- Spotted Gar
- Shortnose Gar
- Florida Gar
- Tropical Gar
- Alligator Gar
- Cuban Gar
1. Longnose Gar (Lepisosteus osseus)
Scientific name – Lepisosteus osseus
Identification: Recognizable by its very long, narrower snout compared to other large gar. Its torpedo-shaped body is typically olive-brown.
Distribution: Widespread in eastern North America, from Quebec to Florida, throughout the Mississippi River basin (including states like Ohio and Missouri) and into Texas.
Size and age – The male longnose can survive for 17 years, and females can live for 22 to 30 years. It can reach a length of about 2.5 feet.
Habitat – They live in freshwater lakes and brackish water in and around swamps, and coastal areas, as well as the sluggish backwaters of streams and rivers.
Spawning season – The spawning season occurs in the spring and the summer. During this time, the longnose gar swims upstream to spawn and then moves back downstream into larger pools.
Diet: Primarily smaller freshwater fish; not typically known to consume turtles or crabs.
Eating: Longnose gar meat is edible and considered good by some.
2. Spotted Gar (Lepisosteus oculatus)
Scientific name – Lepisosteus oculatus
Identification – This garfish is cylindrical and is often confused with a log in shallow waters. They have hard ganoid scales and spots that extend from the top of the head to the fins.
Distribution – This gar lives throughout the drainages in the Erie and Michigan Lakes. The fish also thrives in the Mississippi River, all the way up to the northern coast of Mexico.
Size and age – These species of gar rarely grow more than 34 inches, with most topping at 30 inches. Males can live for eight years, while females can live for ten years.
Habitat: Thrives in clear, shallow waters with vegetation, common in the Mississippi River system and parts of the Great Lakes drainages.
Spawning season – Spawning occurs from February to June and varies with location.
Food – This gar feeds primarily on aquatic crustaceans such as crayfish as well as other species of the dish such as bass, catfish, shiners, and crappies.
3. Shortnose Gar (Lepisosteus platostomus)
Scientific name – Lepisosteus platostomus
Identification: Distinguished by its relatively short, broad snout but lacks the double row of teeth of the Alligator Gar.
Distribution: Common in the Mississippi River and its major tributaries like the Missouri River.
Size and age – The shortnose gar can grow as big as 24 inches and can live for 20 years.
Habitat – These species inhabit calm waters in large rivers and backwaters as well as quiet pools where it likes to remain around downed logs and vegetation.
Spawning season – Shortnose gar starts to spawn in early to mid-April till the end of May.
Food – Shortnose gar usually feed on invertebrates and other gar species.
4. Florida Gar (Lepisosteus platyrhincus)
Scientific name – Lepisosteus platyrhincus
Identification – This fish has black spots on the top of its head and over its entire body that are round and irregular. These spots are also on the anal fin. The snout is broad and short, and it is olive brown with a yellow underbelly.
Distribution – Florida gars can be found from the River drainage Savannah in Georgia to Ochlocknee in Florida.
Size and age – This Florida fish can grow to about 20 to 50 inches in length. While data is limited regarding the lifespan of this species, like most gar, it should be able to live for 18 years on average.
Habitat – This gar inhabits medium to large canals, lowland streams, and lakes that have sandy or muddy bottoms and which are near vegetation.
Spawning season – This gar spawns once a year, and the spawning season occurs from February to April.
Food –This gar feeds on shrimp, fish, and crayfish.
5. Tropical Gar (Atractosteus tropicus)
Scientific name – Atractosteus tropicus
Identification – Tropical gar have short, broad snouts and nostrils at the front of the muzzle. Their teeth are long and fang-like, and their scales are smooth and shiny.
Distribution – Can be found in the Caribbean and Pacific drainages of Central America and southern Mexico.
Size and age – This tropical river gar can grow to about 20 or 23 inches in length and can live for 25 years.
Habitat – This gar can be found in backwaters and slow-moving parts of lakes, rivers, and shallow lagoons. The fish can sometimes be found floating on the surface of the water.
Spawning season – The spawning season falls in June and July, as well as the dry season.
Food – This gar mainly feeds on cichlids and other fish, but it is also known as insects, copepods, and plant material.
6. Alligator Gar (Atractosteus spatula) – The Giant of the Gar Family
Scientific name – Atractosteus spatula
Identification: The largest gar species. Distinctive for its broad, alligator-like snout and two rows of large, sharp teeth in the upper jaw. Its body is heavily armored with thick, interlocking ganoid scales.
Distribution: Historically widespread in the Mississippi River basin and Gulf Coastal states of the United States, from Florida to Texas and into Veracruz, Mexico. Now, populations are more concentrated in areas like Texas, Louisiana, and parts of the lower Mississippi River. Found in large rivers, reservoirs, bayous, and estuaries.
Size, Age & Records: Can grow to immense sizes. The largest gar on record (and biggest gar ever caught by various methods) are typically Alligator Gar. Fish over 8 feet and 300 pounds have been documented. For example, a well-known 283-pound Alligator Gar was caught in Texas. They are slow-growing and long-lived; a 7-foot Alligator Gar could be several decades old.
Habitat – Alligator gar is usually found in lakes and reservoirs in backwaters of lowland rivers. This includes bodies of water that experience low currents such as brackish marshes that it does not have to struggle to swim in. This includes ‘dead lakes’, a body of water that is inundated by an adjacent river when the water level rises and which is landlocked at normal levels
Spawning season – Alligator gar breed once a year between May and July.
Diet: Apex predators feeding on a wide variety of freshwater fish, but also known to take turtles, waterfowl, and small mammals. Not typically known to eat crabs.
- Conservation & Human Interaction:
- Is Alligator Gar endangered? Not federally listed as endangered in the United States, but some states list them as threatened or have specific conservation programs due to historical overfishing and habitat loss. Some areas have strict regulations or protections.
- Why is gar a “bad fish to catch?” Historically, some viewed them as “trash fish” detrimental to game fish populations, leading to eradication efforts. This view has largely changed with better understanding of their ecological role. They are now prized sportfish in many areas.
- Has a gar ever attacked a human? Confirmed unprovoked attacks are extremely rare to non-existent. Their sharp teeth demand respect when handling, but they are not inherently aggressive towards humans in the water.
- Rare Variants: While extremely uncommon, “platinum” or “golden” color morphs of Alligator Gar (and other gar species) are occasionally reported by aquarists or seen in the wild.
7. Cuban Gar (Atractosteus tristoechus)
Scientific name – Atractosteus tristoechus
Identification – The Cuban gar has a smooth body with no patterns or spots. It also has a mottled, orange tale.
Distribution – This endangered gar can be found in the rivers and lakes of western Cuba and the Isle de la Juventud.
Size and age – Adult Cuban gars, can grow to about 3.3 feet in length, but some have been known to grow as large as 2 meters. There is currently no information available about the lifespan of these species.
Habitat – Cuban gar inhabits brackish waters in rivers and lakes, and it is a freshwater species.
Spawning season – There is currently no information available about the spawning season of this gar, but like most garfish, it is assumed that it spawns from early to April to the end of May or June.
Food – Adult Cuban gar feeds on freshwater fishes and even birds.
Conservation: Faces significant threats from habitat degradation and overfishing, highlighting the importance of conservation efforts for this unique gar species.
General Gar Characteristics
- Scales: All gar possess hard, diamond-shaped ganoid scales that form a protective armor.
- Air Breathing: Their ability to gulp air using their modified swim bladder allows them to survive in waters with low oxygen levels, a trait common to the Lepisosteidae family.
- Predators: As effective predators, they play an important role in their aquatic habitats.
- Spawning & Eggs: Most gar species spawn in shallow, vegetated waters during spring or early summer (e.g., April to June). The eggs of all gar are adhesive and, importantly, toxic to mammals and birds if ingested.
Frequently Asked Questions About Gar (Consolidate & Refine)
There are seven recognized living species of gar in the family Lepisosteidae. The Alligator Gar is the largest, while species like the Cuban Gar are among the rarest due to their limited range and conservation status.
Yes, the meat is edible (some compare its texture to chicken or even lobster, though taste is subjective). Crucially, gar eggs (roe) are highly toxic and must never be eaten.
