Needlefish are slender, elongated fish found in warm coastal waters around the world. They belong to the family Belonidae and are known for their sharp, pointed jaws filled with needle-like teeth. These fish can grow up to 3 feet long and are often seen swimming near the surface, where they hunt small fish and invertebrates. These fish are typically green or blue on top and silver on the sides, providing camouflage in their aquatic environment. Needlefish are known for their unique swimming style, which involves rapid bursts of speed. They are also capable of leaping out of the water, a behavior that can help them evade predators like dolphins and seabirds.
