A boat collided with a whale off the Jersey Shore Saturday afternoon, killing the 20-foot-long animal and throwing one passenger overboard.

Social media video shows the boat swaying side to side upon impact with the whale, as a boater is tossed into the waters of New Jersey’s Barnegat Bay. The mammal — later identified as a minke whale — can then be seen slowly swimming away from the vessel.

“Oh my God, they’re going over,” a witness to the incident can be heard saying in the dramatic video. “Ooh, man overboard!”

Officials said the person sent overboard is believed to be OK, CBS News reported.

Boaters — for their own safety — have been urged to stay at least 150 feet away from the whale’s remains in the meantime.

Earlier this year, a humpback whale swallowed a man on a kayak off the coast of Chile, before he was quickly able to get out of the leviathan’s mouth unharmed.

The Marine Mammal Stranding Center, the U.S. Coast Guard and the NJ State Police Marine Unit did not immediately respond to Fox News Digital’s request for comment.
