There are around 264 species of fish found in 6 families in this order.  They are known for their long, slender bodies and, in many species, their sharp, beak-like jaws. This order includes needlefish, halfbeaks, viviparous halfbeaks, and flying fish.

Beloniformes are usually found in warm oceans, though some species live in freshwater. Many swim close to the surface, where they feed on smaller fish, plankton, and insects. Their streamlined bodies help them move quickly through the water.

One of the best-known families in this order is the flying fish. These fish can leap out of the water and glide through the air for impressive distances using their large, wing-like fins. This helps them escape predators.

Another interesting feature of some Beloniformes is their unusual jaw shape. For example, halfbeaks have a longer lower jaw than upper jaw, which helps them scoop up food at the water’s surface.

The Atlantic needlefish (Strongylura marina) is found along the Atlantic Coast from Maine to Brazil, as well as in the Gulf of Mexico.
