The Barracuda, usually known as Picúa (Sphyraena barracuda) inhabits tropical waters and can measure about 2 meters long.
It is a curious and extremely quick animal with razor-sharp teeth and powerful jaws of which the bites could cause serious bleeding.
They are attracted by brilliant objects that reflect light and by captured fish, therefore often they can be found near submarine fishermen.
You should not dive in cloudy
waters and avoid to harpoon it; since when they defend themselves, they
could cause sometimes serious injuries.
