Bull Shark

The bull shark is a sturdy shark with a broad snout, found mainly in warm coastal waters. It can tolerate a wide range of salinities and may enter rivers and other freshwater habitats. Fish and other animals make up its diet. Movement between salt and fresh water involves physiological control of the body's salts and water. Shallow estuaries can provide important habitat for young sharks. The species' broad environmental tolerance distinguishes it from many sharks that remain in marine waters.
