Needlefish vs. Garfish — What's the Difference?
By Tayyaba Rehman & Urooj Arif — Updated on March 31, 2024
Needlefish inhabit marine areas with streamlined bodies; garfish, with harder scales, live in freshwater. Both have elongated bodies and sharp-toothed jaws.

Key Differences
Needlefish are known for their slender, streamlined bodies and long, narrow jaws, making them efficient predators in marine environments. They are surface dwellers, often found in shallow coastal waters or estuaries, and can leap out of the water at high speeds. Whereas garfish, a common term that often refers to members of the gar family (Lepisosteidae), inhabit mostly freshwater environments, including lakes, rivers, and swamps, though some species can venture into brackish waters. Gars have elongated bodies too, but they are distinguished by their ganoid scales, which are hard and diamond-shaped, providing them with extra protection.
The diet of needlefish primarily consists of smaller fish and occasionally crustaceans, which they catch with their sharp teeth during swift attacks. Garfish, on the other hand, have a similar diet but can also include a wider variety of prey due to their habitat diversity, ranging from small fish to aquatic invertebrates. Their method of hunting is also predicated on ambush, using their long bodies to rapidly strike at prey.
Another notable difference is in their reproductive behaviors. Needlefish spawn in shallow waters, laying eggs that attach to vegetation or the sea floor, while gars lay adhesive eggs that stick to underwater vegetation, a trait that helps protect the eggs from being swept away or eaten by predators.
In terms of human interaction, needlefish are sometimes considered a hazard due to their tendency to leap above the water's surface, potentially injuring boaters and swimmers. Gars, with their tough scales and formidable appearance, are often caught for sport, though their flesh is not commonly consumed due to its bony nature. However, in some cultures, gar eggs are considered toxic and should be avoided.
Despite these differences, both needlefish and garfish share adaptations that make them effective predators in their respective environments, including their long, tooth-filled jaws and streamlined bodies, highlighting the diverse strategies of aquatic life in exploiting ecological niches.

Needlefish
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.
Garfish
The garfish (Belone belone), also known as the garpike or sea needle, is a pelagic, oceanodromous needlefish found in brackish and marine waters of the Atlantic Ocean and the Mediterranean, Caribbean, Black, and Baltic Seas.

Common Curiosities
How do needlefish and garfish differ in appearance?
Needlefish have streamlined bodies with smooth scales and long, narrow jaws, whereas garfish have elongated bodies covered in hard, ganoid scales, with long snouts that house their sharp teeth.
What environments do needlefish and garfish inhabit?
Needlefish primarily inhabit marine and brackish waters, often near the surface, while garfish, particularly those in the gar family, are found in freshwater environments, with some species also living in brackish waters.
Are needlefish and garfish related?
Despite some similarities in appearance and diet, needlefish and garfish belong to different families and have distinct evolutionary paths, reflecting their adaptation to different ecological niches.
How do needlefish and garfish reproduce?
Needlefish spawn in shallow waters, where their eggs attach to vegetation or the sea floor, whereas garfish lay adhesive eggs that stick to underwater vegetation, ensuring their eggs' safety from predators and currents.
Are garfish eggs safe to eat?
Garfish eggs are considered toxic and should be avoided, in contrast to the edible flesh of the fish itself, which is not commonly consumed due to its bony nature.
Why are needlefish considered a hazard?
Needlefish are considered a hazard because of their tendency to leap out of the water, which can result in injuries to boaters and swimmers.
How are needlefish and garfish viewed in terms of fishing?
Needlefish are less commonly targeted by fishermen due to their leaping behavior and slender bodies, while garfish are often sought after for sport fishing because of their size, strength, and prehistoric appearance, though their flesh is less commonly consumed.
What makes garfish scales unique?
Garfish scales are unique due to their hard, ganoid composition, which provides extra protection against predators and environmental hazards.
What do needlefish and garfish eat?
Both needlefish and garfish are predators that feed on smaller fish, but garfish can also consume a wider variety of aquatic invertebrates due to their diverse freshwater habitats.
Can both needlefish and garfish be found in the same environment?
While it's possible for their habitats to overlap in brackish waters, needlefish are more commonly found in marine environments, and garfish are predominantly freshwater fish, making such occurrences rare.
