VIDEO: Whale And Swimmer Cross Paths Off Plum Island

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.

The swimmer continues to cruise on by as the whale briefly surfaces for air.

Last month, a lobster diver said he was nearly swallowed whole by a whale off Cape Cod.
