A fascinating video has captured the heart-pounding moment two enormous whales are recorded "mugging" a boat filled with tourists.
The video shows two gray whales splashing within mere inches of the Shearwater boat, which is the wildlife-watching vessel, which sails out of Newport Beach in the US state of California.
The vessel, which can hold up to 15 people, is operated by Newport Coastal Adventure who called it "one of the most epic gray whale encounters of all time".
