Lepisosteidae
Gars are members of the family Lepisosteidae, which are the only surviving members of the Ginglymodi, an ancient holosteian group of ray-finned fish, which first appeared during the Triassic, over 240 million years ago. Gars comprise seven living species of fish in two genera that inhabit fresh, brackish, and occasionally marine waters of eastern North America, Central America and Cuba in the Caribbean, though extinct members of the family were more widespread. Gars have elongated bodies that are heavily armored with ganoid scales, and fronted by similarly elongated jaws filled with long, sharp teeth. Gars are sometimes referred to as "garpike", but are not closely related to pike, which are in the fish family Esocidae. All of the gars are relatively large fish, but the alligator gar (''Atractosteus spatula'') is the largest; the alligator gar often grows to a length over and a weight over , and specimens of up to in length have been reported. Unusually, their vascularised sw ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Atractosteus Spatula
The alligator gar (''Atractosteus spatula'') is a ray-finned euryhaline fish related to the bowfin in the infraclass Holostei . It is the largest species in the gar family, and among the largest freshwater fish in North America. The fossil record traces its group's existence back to the Early Cretaceous over 100 million years ago. Gars are often referred to as "primitive fishes", or "living fossils" because they have retained some Morphological (biology), morphological characteristics of their early ancestors, such as a spiral valve intestine, which is also common to the digestive system of sharks, and the ability to breathe both air and water. Their common name was derived from their resemblance to the American alligator, particularly their broad snouts and long, sharp teeth. Anecdotal evidence suggests that an alligator gar can grow up to in length. The body of an alligator gar is torpedo-shaped, usually brown or olive, fading to a lighter gray or yellow ventral surface. ...

Atractosteus Tristoechus
The Cuban gar (''Atractosteus tristoechus''), also known as the manjuarí, is a fish in the family Lepisosteidae. It is a tropical, freshwater species, although it also inhabits brackish water. It is found in rivers and lakes of western Cuba and the Isla de la Juventud. The flesh of the fish is edible, but the eggs are poisonous for humans.Lee, D.S., S.P. Platania and G.H. Burgess, 1983. Atlas of North American freshwater fishes, 1983 supplement. Occasional Papers of the North Carolina Biological Survey no. 1983-6. North Carolina State Museum of Natural History, Raleigh, N.C. 67 p. Cuban gar spawn seasonally in the floodplains of large rivers.Dean B. (1895) The early development of gar-pike and sturgeon. ''Journal of Morphology'' 11, 1–53.
