Once upon a time, you decided to swim in the ocean on a boat. When you were already far from the shore, you noticed some movement in the water... Stopping the boat and looking down, you saw a HUGE ORCA... it was just swimming around the boat, as if examining it... and then you.. Having looked around you did not see a flock of killer whales. Maybe this one got lost from the pack? Who knows... but the fact remains - a huge killer whale is swimming near your boat.
