In a rare display, more than a thousand dolphins stampeded off the coast of Southern California, captivating onlookers on a whale-watching boat.
Footage of the stampede, captured by tour company Dolphin Safari, has attracted hundreds of thousands of views since going online Sunday. Watch:
"The line of dolphins could be seen miles away churning up the water," the company wrote on its YouTube page along with the amazing footage above.
"The dolphins turned and stampeded directly over to the boat. Often this behavior happens without warning or anything frightening them as was the case this time."
Dana Point, Calif., where the video was taken, has the greatest density of oceanic dolphins per square mile "of anywhere in the world," according to Dolphin Safari.
Pretty amazing creatures and footage.
