In the Indo-Pacific region, they are found across the Red Sea and Eastern Africa till Hawaii.
Great barracuda inhabit the marine tropical and sub-tropical waters. The shallow waters with submerged reefs, coral heads, coastal lagoons, open sea and mangroves are home to the great barracudas.
Great barracuda are solitary hunters. Juvenile barracudas form a large school of hundreds and thousands which also protects them from predators. Great barracudas are ambush predators. They camouflage themselves near sea grass and attack the prey by overrunning them with short brush of speed.

They breed few times during the breeding season and release about 5,000 to 30, 000 eggs each time. Great barracuda exhibits dioecism. They mate in the shallow waters when the water becomes warm. The female releases the eggs and leaves it floating in the water until it is hatched. The baby fish or fry, takes shelter in the shallow water and estuaries until they are mature enough to venture out in the open sea.
The larvae settle in shallow waters where there is marine vegetation where it gets protection and food. They spend the first year of their life in shallow estuaries. As they mature, they venture out into the deep sea with reefs.
Great barracudas have an average lifespan of about 14 years.
Great barracuda have sharp eyesight and strong jaws which make them one amongst the few of the predators on top of the food chain. They are carnivorous and feed mostly on small fishes such as grunts, snapper, bream and mullets and occasionally shrimps and other marine invertebrates.

Great barracuda population has remained stable and is not considered an endangered and threatened species. Earlier they were hunted down for their meat. Recently discovery proves that the majority of Great barracudas have high content of toxin causing ciguatera fish poisoning. Consuming fishes with this toxin causes illness, digestive related problems, physiological problems, headaches, muscle pain, fluctuation in blood pressure, heart problems etc. Juvenile barracudas or the ones below 2 feet in length can be consumed. The larger ones however, are considered dangerous and were made illegal to sell in United States.
