Some species of barracuda are reputed to be dangerous to swimmers. Barracudas are scavengers, and may mistake snorkelers for large predators, following them hoping to eat the remains of their prey. Swimmers have reported being bitten by barracudas, but such incidents are rare and possibly caused by poor visibility.
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.
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 ocean's primary producers, mainly contained in phytoplanktons, produce food energy and biomass photosynthetically from sunlight and are the raw fuel for the ocean food webs. Forage fish transfer this energy by eating the plankton and becoming food themselves for the top predators. In this way, forage fish occupy the lower-central positions ...
Populations of large predatory fish in the global oceans were estimated to be about 10% of their pre-industrial levels by 2003, [1] and they are most at risk of extinction; there was a disproportionate level of large predatory fish extinctions during the Cretaceous–Paleogene extinction event 66 million years ago.

In the ocean food chain, large sharks generally only have to worry about keeping orcas at bay — but a new study suggests the apex predators may have to watch out for their own.. Researchers have ...
The main food is other fish but sometimes includes cephalopods and crustaceans. They are a social species and large groups of Sphyraena sphyraena numbering between ten and two hundred have been recorded. [9] Reproduction occurs between May and August and the female can lay up to 300,000 eggs. [7]
Shocked researchers are trying to figure out what kind of apex predator took out an 8-foot-shark as it wandered through the oceans — and they think it might have been another, bigger shark.
