Planet Ocean Learning Adventures: Barracuda

Planet Ocean Learning Adventures: Barracuda
Discovery Education

Take one look at a great barracuda's toothy grin and you'll understand why it has earned the nickname "Tiger of the Sea."

With its sleek, torpedo-like body, dagger-like teeth, and ferocious appetite, the barracuda is built to hunt in the ocean. And that's exactly what it has been doing for the last 50 million years. Any diver who's seen a barracuda attack another fish can tell you that it happens faster than you can say "anchovy." One moment, a barracuda will be drifting lazily among the coral reefs. The next, it's rocketing toward a fish and snapping it up in its jaws

So, is the barracuda a cold-blooded killer? You betcha! A barracuda is a predator because it needs to eat to survive. And it's cold-blooded because all fish are cold-blooded. They adapt to the temperature of the water surrounding them.
