Sphyraena barracuda is a species of predatory fish found in the tropical and subtropical waters of the world's oceans. While it is commonly known as barracuda, there are several other synonyms for this fish, including Cuda, Sargeant fish, Saw-toothed barracuda and Great barracuda. These synonyms are often used in different regions of the world or by different fishing communities. Barracudas are known for their elongated bodies, sharp teeth, and fast swimming speeds, which allow them to ambush prey in open water. While barracudas are often sought after by anglers for sport, they are also an important commercial fishery in tropical regions.
