The bull shark has a short snout that is wider than it is long (hence its name). Its belly is off-white, its top surface is gray, and the eyes are small. The first dorsal fin is much longer and more pointed than the second dorsal fin. A pup's fins have black tips, but these marking fade in the adults. The females are larger than the males. The bull shark is also know as the cub, Ganges, Nicaragua, river, Swan River Whaler, Zambezi, shovelnose, slipway grey, square-nose, and Van Rooyen's shark.
Bull shark teeth are triangular, serrated (saw-edged), and very sharp.
The teeth are located in rows which rotate into use as needed. The first two rows are used in obtaining prey, the other rows rotate into place as they are needed. As teeth are lost, broken, or worn down, they are replaced by new teeth that rotate into place.
On average, adult males are about 7 feet (2.1 m) long weighing 200 pounds (90 kg). Adult females are about 11.5 feet (3.5 m) long weighing 500 pounds (230 kg).
DIET AND FEEDING HABITS
The bull shark eats fish (including other sharks and rays), turtles, birds, mollusks, crustaceans, and dolphins. It will eat almost anything.
