Barracuda
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 can reach up to 2.1 m (6.9 ft) in length
and 30 cm (12 in) in width.[2][3] The barracuda is a
saltwater fish of the genus Sphyraena, the only genus
in the family Sphyraenidae, and is found in tropical and
subtropical oceans worldwide ranging from the Eastern
border of the Atlantic Ocean to the Red Sea and
Caribbean Sea. They are found near the top of the water
and near coral reefs and sea grasses
Appearance and physical description
Barracudas are snake-like in appearance, with prominent, sharp-edged, fang-like teeth, much like piranhas, 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 blue, dark green, 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.
Behavior and diet
Barracudas are voracious, opportunistic predators,
relying on surprise and short bursts of speed
(up to 27 mph (43 km/h))[5] 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). They kill and consume larger prey by tearing chunks of flesh. Barracuda are competitive species and often are seen competing against mackerel, needle fish and sometimes even dolphins for prey.[4]
It is known that Barracuda feed on an array of prey including fishes such as jacks, grunts, groupers, snappers, small tunas, mullets, killifishes,
herrings, and anchovies by simply biting them in half.[6]
They also seem to consume smaller species of sustenance
that are in front of them.
Interactions with humans
Like sharks, some species of barracuda are reputed to be
dangerous to swimmers. Barracudas are scavengers, and
may mistake snorkellers for large predators, following
them hoping to eat the remains of their prey. Swimmers
have reported being bitten by barracuda, but such incidents
are rare and possibly caused by poor visibility. Large
barracudas can be encountered in muddy shallows on
rare occasion. Barracudas may mistake things that glint
and shine for prey.[7] One incident reported a barracuda
jumping out of water and injuring a kayaker,[8] but Jason Schratwieser, conservation director of the International Game Fish Association, said that the wound could have been caused by a houndfish.[9]
Handfeeding or touching large barracudas in general is to be avoided. Spearfishing around barracudas can also be dangerous, as they are quite capable of ripping a chunk from a wounded fish thrashing on a spear.
As food
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 food poisoning.[10] 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.[6]
West Africans smoke them for use in soups and sauces. Smoking protects the soft flesh from disintegrating in the broth and gives them a smoky flavor.
