Genus Sphyraena, commonly known as barracuda, is a genus of predatory fish found in tropical and subtropical waters around the world. There are several synonyms for this genus, including Belone, Esox, Harengula, and Pythiosoma. These synonyms were used by different scientists and taxonomists at different times throughout history to refer to barracuda or similar-looking fish. Despite the varying names, all species in the genus Sphyraena share similar physical characteristics such as elongated bodies, large mouths filled with razor-sharp teeth, and a tendency to camouflage themselves in their surroundings. While these fish are often sought after by fishermen for their food value and sport fishing opportunities, they also play a vital role in the ocean's ecosystem as top predators.
