Whales can talk with other whales at several km. I'm unsure about what I'm seeing in the small scaled video, but there is not necessarily a physical collision here. A "Sonic wave collision" is much more probable. Also the ocean is a 3D mass of water. A sperm whale crossing the path of a ship could be perfectly at 800m of distance while doing it. (Probably not this particular case, I assume that the antenna can only work at surface, but we should take a look to the article methodology before to conclude that the whale is moving to avoid to crash with the ship).
