WhyReef - Fun Facts
A vicious predator, the great barracuda is one of the scariest looking fish on the reef. You can find it swimming with its mouth open, showing off its long knife-like teeth, which it uses to slice large fish in half so it can eat them! If it is hunting fish near the bottom of the reef, it can darken its skin color to blend in and catch prey by surprise. This strategy is one example of cryptic coloration—the ability of many animals to use their skin color to blend in to their surroundings and remain unseen.
