Though enthusiastic discussion and vivid images author and Field Naturalist Peter Trull will discuss and explain the relationship between commercial fishing, expanding Gray Seal populations, and Great White Sharks along the beaches of Cape Cod and the northeast coast.

This "Gray Curtain" has come about after geologic and environmental changes, as well as animal migrations and population increases. Each has had an effect on the location and, though daily and seasonal changes are accepted as normal, there are great transformations taking place that may go unnoticed, some, unexplained.

While fishermen and scientists don't always agree, both have played a role in these dynamic coastal changes. In the minds of many commercial fishermen, the Gray Seal has played a major part.

Now, a new charismatic, apex predator has entered the picture and has made its presence known: the Great White Shark. This enlightening and colorful program will bring together the main factors that have created the phenomenon of The Gray Curtain.
