Gar-pike (Belone), a genus of bony fishes in the family Scombresocidae, not far from the true pikes (Esocidae). They have long bodies, and both jaws are prolonged into a slender beak, beset with roughnesses and widely set teeth. They swim actively, with an undulating motion, near the surface, and catch small fishes in their jaws. The common Gar-pike (B. vulgaris or B. belone) is frequent off British coasts, and is sometimes called Greenbone, from the colour of the bones (especially after cooking), Gorbill, from its characteristic beak, or Mackerel-guide, because it visits the coasts just before the mackerel. It is usually about two feet in length, is often brought to the London market, and forms a wholesome dish, in flavour somewhat like mackerel. About fifty species are known from tropical and temperate seas, some twice as long as the British species. The young forms have at first jaws of a normal size, and in growth the lower outstrips the upper. The name Gar-pike is sometimes applied to the far-removed Ganoid, Lepidosteus, or Bony Pike (q.v.).
