Atractosteus (from Greek atractos, 'spindle', and osteos, 'bone')[4] is a genus of gars in the family Lepisosteidae, with three extant species. It is one of two surviving gar genera alongside Lepisosteus.[5]
The three surviving species are all widely separated from one another, with A. spatula being found in the south-central United States, A. tropicus in southern Mexico and Central America, and A. tristoechus in Cuba.[5] Although generally inhabiting fresh water, they are tolerant of marine conditions.
