PLUM ISLAND (CBS) — A whale and swimmer had a close encounter off Plum Island Thursday morning. Luckily, no one ended up in a whale’s mouth this time.

Ann-Margret McDade filmed what she believed to be a right whale feeding next to a swimmer. There are fewer than 400 of the endangered whales left in the ocean.
