[19] The great barracuda is present in tropical to warm temperate waters, in subtropical parts of the Indian, Pacific, and Atlantic oceans.

Primarily found in oceans near the equator, these Great Barracuda find refuge in mangrove areas to deep reefs, and seagrass beds, with a lower depth limit of 110 meters (360 ft).

[13][14] Studies conducted by a research group tagging and monitoring these fish in the Bahamas concluded that a good amount of the population of Barracuda stays in their residential habitats for a long period.

Barracudas possess strong, fang-like teeth that are unequal in size and set in sockets in the jaws and on the roof of the mouth.

But requires multiple bites and lateral shaking of the head to reduce the prey to smaller pieces and move towards the anterior portion of the mouth to be eaten.

Their fish diet consists of killifishes, herrings, sardines, gobies, silversides, anchovies, small mullets, and lizardfishes, to name a few.

Large barracudas, when gorged, may attempt to herd a school of prey fish in shallow water where they guard over them until they are ready for another hunt.

Barracudas are scavengers, and may mistake snorkelers for large predators, following them in hopes of eating the remains of their prey.

However they are also known for the pungent odor they release upon being caught, and their meat has a chance of causing Ciguatera fish poisoning when eaten.

[2] Studies have proven that fishing-related stressors can reduce the Barracuda’s physical capability of evading to a refuge for protection.

[18] Having impaired cognitive or visual acuity limits their ability to locate their refuge areas, increasing their chances of predation.

[18] There have been some instances of seeing and catching these Great Barracudas in areas outside their normal subtropical and tropical habitats, such as the Canadian oceans and the North-East Atlantic.
