Gars (Ginglymodi, Lepisosteiformes) belong to the family Lepisosteidae and are among the most primitive of predatory fishes. Together with their closest relatives the bowfins, they make the group Holostei.

Gars are easily identified from other fishes by their elongate snout (uniquely elongate in the ethmoid region of the skull) containing numerous conical sharp teeth and their interlocking, diamond-shaped ganoid scales (Polypterids also possess ganoid scales, but are different in composition).
Lepisosteids possess a modified gas bladder (highly vascularized; connection between throat and gas bladder) which serves as a lung for facultative air-breathing. Gars breathe air when activity levels are high and/or dissolved oxygen levels are low.
Although once found on several continents, extant members of this family are presently relegated to North & Central America and Cuba, represented by two genera and seven species.

Gars are my favorite fish. There is a soft spot in my heart for what others consider to be junk fish.
A living dinosaur that deserves to be protected at all costs
Looking forward to additional pictures
