Characteristics of Needlefish
Needlefish, also known as garfish or longtom, belong to the family Belonidae. They are characterized by their streamlined bodies, long, narrow jaws filled with sharp teeth, and a single dorsal fin positioned far back on their body. In Australia, several species of needlefish can be found, including the Slender Longtom (Tylosurus acus) and the Stout Longtom (Tylosurus gavialoides).
Behavior and Habitat
Needlefish are primarily found in shallow coastal waters, estuaries, and sometimes even freshwater environments. They are highly predatory, feeding on smaller fish and crustaceans. Their long, narrow jaws allow them to dart quickly through the water, capturing prey with precision.
Risks to Humans
While needlefish are generally harmless, they can pose a risk to humans, particularly to swimmers and surfers. These fish are known to leap out of the water, sometimes striking unsuspecting individuals. Their sharp teeth can cause painful puncture wounds that may require medical attention.
To minimize the risk of injury, it is advisable to avoid swimming or surfing in areas where needlefish are known to congregate. If you are in the water and see a needlefish approaching, it is best to exit the water immediately.
Conservation Status
Most needlefish species in Australia are not considered threatened or endangered. However, it is important to protect their habitats and maintain healthy marine ecosystems to ensure their long-term survival.
Needlefish are an intriguing part of Australia's marine biodiversity. While they can pose a potential risk to humans, it is important to appreciate their role in the ecosystem and take necessary precautions to avoid injury. By understanding their behavior and habitat, we can coexist peacefully with these fascinating creatures.
