The barracuda (Sphyraenus, family Sphyraenidae) is a ray-finned fish notable for its large size (up to 1.8 m or 5 ft) and fearsome appearance. The one genus of the family includes about 25 known species.
The barracuda body is elongated, with the lower jaw of the large mouth jutting out, and displaying prominent fang-shaped teeth. The two dorsal fins are widely separated, with the first having five spines and the second one spine and nine soft rays. The lateral line is prominent.
They are caught as food and game fish (however, barracuda flesh can occasionally contain ciguatera toxin).

Behavior
Diver_in_school_of_barracudas.jpg
Barracudas occur solitairy and schools around reefs, but also appear in open seas. They are voracious predators and hunt using a classic example of lie-in-wait or ambush. They rely on surprise and short bursts of speed to overrun their prey, sacrificing maneuverability.
There have been a few isolated cases where barracudas attacked a human thinking that part of it was a fish, but these incidents are extremely rare; especially when considering the number of times that barracudas and humans meet each other.
While barracudas sometimes follow snorkelers and scuba divers across the reef, which can make one feel uncomfortable, there exist no substantiated reports of unprovoked attacks on divers. Known incidents generally involve (spear) fishing or hand feeding.
Distribution
Barracudas occur in subtropical and tropical oceans worldwide.
