A drone armed with a GoPro camera has shot a stunning five minute video of a dolphin stampede. The video was shot off the waters of San Clemente, California.

These dolphins were part of a large megapod that has hundreds or sometimes thousands of dolphins. It is said that there are a number of such megapods existing in Southern California.

David Anderson, owner of Whale Safari, a local whale watching group, said a boater saw a mega-pod of dolphins and informed him about it. But by the time Anderson reached on the scene, the dolphins were found in a stampede formation.

Anderson said that the day was clear and sunny and he thought that the day was perfect to test his drone technology. For now, it is not known that what makes dolphin pods to be in a stampede condition. There are some mega-pods that are five miles wide.

"It's mysterious behavior. Scientists don't know exactly what causes dolphin stampedes. I've seen them where they start slow and build up speed, and where they start suddenly with a burst of activity", said Anderson.

Massive hunt for food, an opportunity for mating and common fear of predator can be some of the possibilities for such a stampede formation. Anderson said it was not his boat that caused dolphins to run as the video also shows Capt. Dave's boat. He said dolphins are used to their boats in the region.

It is not the first time when Anderson has used the drone technology. He has recently replaced a drone as his earlier one drowned at sea. The video has let many people think about positive sides of drones as generally they are considered to be affecting the public's privacy.

Anderson said if the drones will be banned then people will not be able to see the lives of these beautiful animals.
