Barracuda are snake-like in appearance, with prominent, sharp-edged, fang-like teeth, much like piranha, all of different sizes, set in sockets of their large jaws.
They have large, pointed heads with an underbite in many species.
Their gill covers have no spines and are covered with small scales.
Their two dorsal fins are widely separated, with the anterior fin having five spines, and the posterior fin having one spine and 9 soft rays.
The posterior dorsal fin is similar in size to the anal fin and is situated above it.
The lateral line is prominent and extends straight from head to tail.
The spinous dorsal fin is placed above the pelvic fins and is normally retracted in a groove.
The caudal fin is moderately forked with its posterior edged double-curved and is set at the end of a stout peduncle.
The pectoral fins are placed low on the sides.
Its swim bladder is large.
Speedy and dynamic, they are slim, with small scales.
Barracudas also have two well-separated dorsal fins, a protruding lower jaw, and a large mouth with many large, sharp teeth.

In most cases, a barracuda is dark gray, dark green, white, or blue on its upper body, with silvery sides and a chalky-white belly.
Coloration varies somewhat between species.
For some species, irregular and unorganized black spots or a row of darker cross-bars occur on each side.
Their fins may be yellowish or dusky.
Barracudas live primarily in oceans, but certain species, such as the great barracuda, live in brackish water.

Some species grow quite large (up to 65 inches or 165 cm in length), such as Sphyraena sphyraena, found in the Mediterranean Sea and eastern Atlantic; Sphyraena picudilla, ranging on the Atlantic coast of tropical America from North Carolina to Brazil and reaching Bermuda.
Other barracuda species are found around the world.
Examples are Sphyraena argentea, found from Puget Sound southwards to Cabo San Lucas, Sphyraena jello, from the seas of India and the Malay Peninsula and Archipelago.
