genus Sphyraena, family Sphyraenidae
The barracuda is a ray-finned fish known for its large size and fearsome appearance. Its body is long, fairly compressed, and covered with small, smooth scales. Some species could reach up to 4 ft. (1.8m) in length. The barracuda is a salt water fish and is found in tropical and subtropical oceans worldwide. [I’ve usually seen them lurking just below the surface or in the shade of the boat, but have never had a problem with them while in the water.]
Barracudas are popular both as food and game fish. Larger species, like the Great Barracuda, have been implicated in cases of ciguatera food poisoning. Southern Nigerians smoke them for use in soups. Smoking protects the soft flesh from disintegrating in the broth.
Barracudas are voracious, opportunistic predators relying on surprise and short bursts of speed — up to 27 miles per hour (43 km/h) — to overtake their prey. They are attracted to bright, shiny objects so it’s best to remove all jewelry before diving or snorkeling
Adults of most species are more or less solitary, while young and half-grown fish (shown) frequently congregate. Barracuda prey primarily on fish (including some as large as themselves). They kill and consume larger prey by tearing chunks of flesh.
