The Longnose Gar (Lepisosteus osseus) is a primitive, prehistoric freshwater and brackish fish. Easily recognized by its torpedo-shaped body and extremely long beak, it offers a fascinating glimpse into the ancient aquatic world of North America.

Physical Characteristics & Size

The Needlenose Gar is built like an armored dart. Its body is covered in hard, diamond-shaped ganoid scales. Coloration typically features an olive-brown to green top that fades to a white or silvery belly, often peppered with dark spots on its fins and body.

This is a massive, formidable species. Adults commonly measure 3 to 5 feet (30 to 60 inches) in length, though exceptional specimens can grow nearly 6 feet long and weigh between 30 and 50 pounds, with females generally growing larger than males. You might also hear them referred to by nicknames like Billyfish, Pin-nose gar, and Scissorlips.

Habitat & Air Breathing

Found widely across eastern and central North America—ranging from Quebec and the Great Lakes all the way down to the Gulf Coast and the Rio Grande—they are incredibly adaptable. They prefer quiet, slow-moving rivers, sluggish backwaters, lakes, swamps, and estuarine environments with overhanging trees and submerged structures.

One of their most remarkable survival traits is their vascularized swim bladder. This specialized organ acts somewhat like a lung, allowing the gar to gulp atmospheric air at the surface and survive in stagnant, low-oxygen waters during warm summer months.

Diet & Behavior

Needlenose Gars are nocturnal, sight-feeding ambush predators. Their hunting strategy is masterful: they float motionless near the surface, expertly mimicking a drifting log. When prey swims too close, they execute a lightning-fast side-swipe with their tooth-filled beak to impale their target.

While they are highly effective predators, their diet primarily consists of small fish, shad, shiners, insects, and crustaceans.

Spawning & Lifespan

These ancient fish spawn in the spring, congregating in shallow water over gravel or vegetation to lay their eggs. Once they pass their vulnerable juvenile stage, they are incredibly long-lived. A Needlenose Gar typically lives 15 to 20 years, though some females have been recorded living up to 30 or 40 years.
