The Great barracuda (Sphyraena barracuda) appears as the “giant” of the barracuda family. It measures around 6.5ft; it is the most impressive species in size. This long fish can weigh up to 110 Lbs. It has a silver-grey color that makes the species difficult to notice in the blue ocean.
The adult barracudas have black streaks on its back part of the body. These streaks help identify each particular individual. The Great barracuda has a large prominent jaw giving it an aggressive aspect.
The Great barracuda lives in tropical waters in all oceans. You can encounter it in the surface waters in the open ocean as well as around the ports. The barracuda is a solitary fish at adulthood. In contrast, young barracudas travel in schools, increasing their chances of survival. The adult Great barracuda have no real natural predators but young individuals are sometimes hunted by giant tunas or sharks…
The Great barracuda is shaped like a torpedo. It hunts its prey with lightning attacks, reaching a maximum speed of 45 Km/h. It uses a well-developed swim bladder as a buoyancy compensator to attain different depths. This predator diurnal, hunts in the day and feeds on small fish, squid, octopi or shrimps. It is a very curious species often approaching divers attracted by their bubbles.
In French Polynesia, the barracuda is a pelagic fish consumed only small proportion because of its presumed link with ciguatera poisoning. Thus, you will probably encounter numerous great barracudas during your next dives in South Pacific waters.
