The ganoids or Ganoidei are an order of fish. The families of this order are chiefly characterized by angular, rhomboidal, polygonal, or circular scales composed of horny or bony plates covered with a thick plate of glossy enamel-like substance.
The ganoids were most numerous in Paleozoic and early Mesozoic times, but are now represented by seven genera: Lepidosteus, the bony pikes or gar-pikes of the North American fresh-water lakes; Polypterus, represented by a single species occurring in rivers of tropical Africa; Calamoichthys, a similar genus found in Old Calabar; Amia, the fresh-water mud-fish of North America; Acipenser, represented by the sturgeon; Scaphirhynchius, best known by the so-called shovel-nosed sturgeon of the Mississippi basin; and the genus Polyodon or Spatularia, the paddle-fishes of the Mississippi and great rivers of China.

The gar-fish (Lepidosteus, bony pike, sea-pike, gar-pike, sea-needle) is a long and slender sea fish of the genus Belone, about 90cm long. The head projects forward into a very long sharp snout. The sides and belly are of a bright silvery colour and the back is green. They are found in North American lakes and rivers.

The saury pike or skipper (Scombresox) is a genus of bony sea fishes closely allied to the gar-pike. They are known as skippers from their habit of leaping out of the water and skimming along its surface.

The Hughes AIM-47 (Falcon) was an American short to medium range air-to-air missile developed as a larger version of the Falcon series of missiles under the name GAR-9 with the objective of arming the abandoned North American F-108 interceptor aircraft. The AIM-47 was an all-weather weapon utilising infra-red and pulsed Doppler radar guidance systems. The warhead was interchangeable, either high-explosive or nuclear, and the AIM-47 had a flight speed of Mach 6.
