Needlefish belong to the family of Belonidae and consist of up to 35 species of silver needlefish. Some of them are found in freshwater, while the others in brackish or coastal waters. They are classified into ten different genera. Some of the famous species are Garfish, giant needlefish, flat needlefish (Ablennes hians), super strike needlefish, and the Atlantic needlefish (Strongylura marina). Needlefish are widely spread creatures, with several of their species found in the Pacific Ocean, the western Atlantic Ocean, and the Mediterranean Sea. Needlefish usually swim near the surface of the coastal waters. Their slender and streamlined bodies help them swim and move quickly just below the surface. Needlefish catch live food that comes near the surface of the water. Needlefish are caught by fishing and consumed by humans with the help of needlefish lures. Needlefish have elongated and thin bodies.

They have a single vertical fin, and the vertical fin is located at the extreme edge of their back. Needlefish have elongated precise-toothed jaws with sharp teeth. Needlefish are oviparous. Their reproduction occurs during May and June. As the larvae grow, their lower jaws grow longer, but their upper jaw and lower jaw become equal in length as they attain maturity. Needlefish grow up to 37 inches long and are identified by their slender, long, sharp teeth.

What is a Needlefish's habitat?

Needlefish are widely spread creatures, with several species found as freshwater needlefish and others in shallow waters. Needlefish live in coral reefs, freshwater, open ocean, coastal waters, and shallow seas. They are marine creatures that usually swim near the water's surface to catch live food. Needlefish are mainly found in the waters near estuaries, rivers, and islands. Needlefish move away from the shore and the coast during the colder months and return again in the spring and the summer seasons when the temperature is high or moderate.

How long does a Needlefish live?

How do they reproduce?

Needlefish are oviparous, which means that they lay their eggs with embryonic development. Their reproduction occurs during May and June; they breed in the coastal waters and release their eggs in the water. They prefer shallow waters to breed and lay their eggs, as there is a large existence of algae and seaweeds, which helps them stick and get entangled in these thread-like structures. As soon as the larvae hatch, it becomes capable and independent of feeding itself. The eggs take 10 to 15 days or around two weeks to hatch. The larvae have short jaws which are of equal length. With maturity, their lower jaws grow longer. Ultimately, their lower jaws grow equal to the length of the upper jaws; thus, both the upper and lower jaws' length becomes equal.

What is their conservation status?

Most of the needlefish species are not extinct or endangered, but there is no information available as a whole for their genus. The garfish, flat needlefish (Ablennes hians), and the Atlantic needlefish (Strongylura marina) are confirmed as of Least Concern by the IUCN, International Union for Conservation Nature.
