The Dorsal Fin

According to a WPRI Eyewitness News news clip, 3 to 4 great white sharks were spotted by a pilot yesterday (07/27/10) off the coast of Chatham, Massachusetts. At least one shark, estimated at 12′ in length, was tagged by a fisherman. Increasing sightings of great white sharks around the Chatham area have been attributed by some researchers to large populations of seals, which are a food source of the sharks.
