Barracuda - WikiHQ

A barracuda is a large, predatory, ray-finned, saltwater fish of the genus Sphyraena, the only genus in the family Sphyraenidae, which was named by Constantine Samuel Rafinesque in 1815. It is found in tropical and subtropical oceans worldwide ranging from the eastern border of the Atlantic Ocean to the Red Sea, on its western border the Caribbean Sea, and in tropical areas of the Pacific Ocean. Barracudas reside near the top of the water and near coral reefs and sea grasses. Barracudas are often targeted by sport-fishing enthusiasts.

Etymology

The common name "barracuda" is derived from Spanish, with the original word being of possibly Cariban origin.

Description

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 carry a striking resemblance to pike, although they are not related. 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 nine 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 edge double-curved and is set at the end of a stout peduncle. The pectoral fins are placed low on the sides. The swim bladder is large, allowing for minimal energy expenditure while cruising or remaining idle.

In most cases, barracuda are dark gray, dark green, white, or blue on the 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. Due to similarities, sometimes Barracuda is compared with freshwater pike, though the major difference between the two is that Barracuda has two separate dorsal fins with a forked tail, unlike the freshwater pike.

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.

A related fossil genus, Parasphyraena, is known from the Miocene of Azerbaijan. to overtake their prey.

Adults of most species are more or less solitary, while young and half-grown fish frequently congregate.

Barracudas prey primarily on fish (which may include some as large as themselves). Common prey fish include jacks, grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies; often by simply biting them in half. They kill and consume larger prey by tearing chunks out of their prey. They also seem to consume smaller species of sustenance that are in front of them. Barracuda species are often seen competing against mackerel, needle fish and sometimes even dolphins for prey. One incident reported a barracuda jumping out of water and injuring a kayaker, but Jason Schratwieser, conservation director of the International Game Fish Association, said that the wound could have been caused by a houndfish.

Fatalities are nevertheless rare. Deaths have been reported in 1947 in Florida, 1957 in North Carolina and 1960 in Florida, again.

As food

thumb|Grilled [[Sphyraena pinguis|red barracuda in Japan]]

Barracudas are popular both as food and game fish. They are most often eaten as fillets or steaks. Larger species, such as the great barracuda, have been implicated in cases of ciguatera fish poisoning. Those who have been diagnosed with this type of food poisoning display symptoms of gastrointestinal discomfort, limb weakness, and an inability to differentiate hot from cold effectively.
