Identification
The longnose gar is a primitive fish with an elongated, cylindrical body covered in hard, diamond-shaped ganoid scales that function as armor. The snout is extremely long and narrow, lined with sharp teeth — hence the comparison to a caiman. Color is olive-green to brown on the back with a lighter belly. Can reach 180 cm but is exceptionally rare in Europe.
Behavior & ecology
The longnose gar is a living fossil: the Lepisosteidae family has existed for over 100 million years and has barely changed. The species has a primitive swim bladder that functions as a lung, allowing it to gulp air at the surface. This enables survival in warm, oxygen-poor water. The longnose gar is a patient ambush predator that hangs motionless in the water and seizes prey (fish) with a quick lateral head movement.
In the Netherlands
The longnose gar is not native to Europe. All finds in the Netherlands result from releases by aquarium keepers. The species is kept as a pet due to its spectacular appearance but outgrows most aquariums. Establishment in the Netherlands is unlikely: the species requires warmer temperatures for successful reproduction.
