Bull Shark

Bull sharks are the most vicious fish in the ocean, or any other body of water on this planet, and they have the strongest bite of all other species of sharks. These sharks have the highest record of human attacks in shallow water. They will eat anything; fish, dolphins, even other sharks. Though humans are not typically in their diet they will attack them on accident or out of curiosity. What is even more terrifying is that they can adapt to fresh water. They have been found in lakes, thousands of miles up the Amazon River, even swimming through flooded streets!
