Pomatomus saltatrix, commonly known as the bluefish, is a species of predatory fish found in both temperate and tropical waters worldwide. They are characterized by their streamlined bodies, sharp teeth, and a bluish-green coloration on their backs, which helps them blend into the ocean environment. Bluefish can grow up to 3 feet long and weigh around 20 pounds. These fish are known for their aggressive feeding behavior and are often sought after by anglers for sport fishing. They primarily feed on smaller fish, such as menhaden and mackerel, and are recognized for their strong fighting ability when caught.
