Bull shark - Bull sharks are distinguished by their blunt nose and stocky build. Bull sharks are a common visitor to local beaches and can tolerate high levels of freshwater. Juvenile bull sharks are common around the beachfront and jetty systems and so are their much larger relatives. They're considered a man-eater. The difference is that a hammerhead has a straight head, while the bonnethead has a rounded one.
Bonnetheads often travel in schools near the water's surface.
Lemon shark - These are one of the largest species of sharks to be found near local beaches. These sharks can weigh more than 500 pounds. They're usually a yellowish-brown color, although some individuals appear to be almost gray. Commercial fisherman Mick Riley was fishing off the coast of Alabama three years ago when he came upon a sight that shocked and disgusted him. There on his line was a completely finless, but still alive 300 pound hammerhead shark.
