Atractosteus tristoechus
An Ancient Gars Lineage Surviving Today
The Cuban gar is one of the larger representatives of the
family Lepisosteidae and one of the most ancient lineages 
of living ray-finned fishes. It has an elongated body, an 
extended snout, and densely arranged sharp teeth, with 
the entire body covered by hard rhomboid ganoid scales, 
displaying the distinctive adaptations of gars. The Cuban 
gar is an ambush predator that primarily feeds on fishes 
and other aquatic animals. Its swim bladder contains a 
rich network of blood vessels and can function as an 
accessory respiratory organ, allowing it to tolerate 
low-oxygen aquatic environments. Gars have a long 
evolutionary history, first appearing in the Mesozoic, and 
have retained many distinctive morphological features. 
They provide important insights into the evolutionary 
history and ecological adaptations of ray-finned fishes.
