Barracuda - Appearance and Physical Description

Appearance and Physical Description

Barracudas are elongated fish, pike-like in appearance, with prominent, sharp-edged, fang-like teeth, much like piranhas, of 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.

In most cases, a barracuda is dark green, dark blue, or gray on its upper body, with silvery sides and a chalky-white belly. Coloration varies somewhat between species. For some species, irregular 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, such as the European barracuda, barracouta, or spet (S. sphyraena), found in the Mediterranean Sea and eastern Atlantic; the great barracuda, picuda or becuna (S. picuda), 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 the California barracuda (S. argentea), found from Puget Sound southwards to Cabo San Lucas, the Indian barracuda (S. jello), and the black-finned or Commerson's barracuda (S. commersoni), from the seas of India and the Malay Peninsula and Archipelago.
