The Grey Seal can reach a weight of well over 800 pounds.  Commonly found in the northern areas of both sides of the Atlantic Ocean, it was aggressively hunted during the last century.  In 1972 Congress passed the Marine Mammal Protection Act which granted protection to the seals, and their numbers rebounded strongly.  The town of Chatham, Massachusetts, a popular summer destination on the “elbow” of Cape Cod, has since seen a dramatic increase in the number of seals that make its sandy coastal areas their home.  But the rise in the number of seals has brought a corresponding increase in the number of their main predator - the Great White Shark (cue scary shark music…).
