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.

An example, which has caused much trouble in Maryland and Florida, is the snakehead fish. [ 5 ] Predatory fish such as sharks , billfish , dolphinfish and tuna form a part of the human diet and are targeted by fisheries , but they tend to concentrate significant quantities of mercury in their bodies because they are high in the food chain ...
Sphyraena barracuda, commonly known as the great barracuda, is a species of barracuda: large, apex predator ray-finned fish found in subtropical oceans around the world. The Syphyraena family contains 27 species while the great barracuda is one of this genus.
The Pacific barracuda is found in the Northeast Pacific Ocean, typically offshore of the U.S. West Coast.While it is usually considered a pelagic species, and can could be found as far north as southern Alaska, they are most frequently found along the coast of California extending down to the southern tip of Baja California Sur, Guadalupe Island and near the mouth of the Gulf of California.
The predatory behaviour of S. viridensis was observed in the same study; they were found to be active pursuit predators of fish, with one or many barracudas hunting together, either singling out lone prey or attacking shoals of prey fish. The pursuit was rapid and was usually over in 8–40 seconds, and the more fish involved, the higher the ...
The blackfin barracuda reaches a maximum size of 140 cm (55 in). The blackfin barracuda is known for its long black lateral bands that go around its body. These bands extend laterally down the torso and are v-shaped with the apex facing to the front. [ 1 ]
Some organisms begin their life cycle as planktonic eggs and larvae, and transition to nektonic juveniles and adults later on in life, sometimes making distinction difficult when attempting to classify certain plankton-to-nekton species as one or the other. For this reason, some biologists avoid using this term.
These small goldband fusiliers are typical forage fish. They swim in large schools for protection from larger predators. Forage fish, also called prey fish or bait fish, are small pelagic fish that feed on planktons (i.e. planktivores) and other small aquatic organisms (e.g. krill).
