Needlefish Is Being Cleaned By Labroides Phthirophagus
Needlefish (family Belonidae) or long toms are piscivorous fishes primarily associated with very shallow marine habitats or the surface of the open sea. Some genera include species found in marine, brackish, and freshwater environments (e.g., '' Strongylura''), while a few genera are confined to freshwater rivers and streams, including ''Belonion'', ''Potamorrhaphis'', and '' Xenentodon''. Needlefish closely resemble North American freshwater gars (family Lepisosteidae) in being elongated and having long, narrow jaws filled with sharp teeth, and some species of needlefishes are referred to as gars or garfish despite being only distantly related to the true gars. In fact, the name " garfish" was originally used for the needlefish '' Belone belone'' in Europe and only later applied to the North American fishes by European settlers during the 18th century.

It is also often called the crocodile needlefish. Description While the houndfish has no spines, its dorsal fin has 21–25 soft rays, and its anal fin has 19–22. They are also known to have 80–86 vertebrae. A key way of distinguishing the houndfish from other members of the genus ''Tylosurus'' is that the houndfish's teeth point anteriorly when the fish is a juvenile. The teeth of other species are straight at all ages.Collette, B.B. 1999 Belonidae. Needlefishes. p. 2151-2161. In: K.E. Carpenter and V.H. Niem (eds.)
