2. Bull Shark
The Bull Shark is strong and very dangerous. It can grow up to 11.5 feet (3.5 meters) long and weigh as much as 700 pounds (318 kg). It lives in both the ocean and fresh water, such as rivers and lakes.
It often swims in shallow water where people swim too. This makes it more likely to come close to humans. There have been over 100 recorded attacks, and many more might not be reported. This shark can appear when you least expect it.
