Brad Rich was sailing near the coast of Seward, which is in Alaska. Suddenly they noticed some humpback whales not so far away. So they began filming the seagulls and hoped to see some whales as well.
Little did they know that the whales are going to give them a big surprise.
Few seconds passed by when the whales showed up and they were so close that they gave gas and had to move.
This size of an animal can easily send the boat underwater with the flick of their tales.
