A Great White Shark attacks a seal decoy off Monomoy Island on Cape Cod, Massachusetts. Since about 2009, this region has become a newly forming hub of white shark activity. The sharks arrive in summer to feed on gray seals. According to historical record, the seals here were wiped out in the late 1600s and have only rebounded in recent years due to the Marine Mammal Protection Act of 1972. Unlike great whites in other regions of the world, the sharks here seem to be using different feeding strategies to hunt the seals, often feeding in shallow water. Among the science being done by researchers is a predation study examining these behaviors.
