The family Belonidae, commonly known as needlefish, includes elongated fish found in warm coastal waters around the world. They are characterized by their long, slender bodies and sharp, pointed jaws filled with needle-like teeth. Needlefish are typically found near the surface of the water and are known for their ability to leap out of the water, often to escape predators. Belonidae species are carnivorous, primarily feeding on small fish and invertebrates. They are often recognized by their distinctive appearance, which allows them to blend into their surroundings, making them effective hunters. Their unique adaptations and behaviors contribute to their role in marine ecosystems.
