Description

The Pacific agujon needlefish is a large needlefish (Belonidae) from warm coastal and surface water of the eastern Pacific. The species can grow to about 1 metre and has a very slender, silvery, torpedo-shaped body with long, thin jaws full of needle-sharp teeth. As a fast predator of the upper layer it hunts small schooling fish. When disturbed it sometimes shoots in a straight line out of the water; its pointed beak can then, or when handled, give a serious puncture or cut wound. Otherwise it is harmless to humans.
