"Dolphin stampedes happen spontaneously and can occur anytime throughout the year," Capt. Dave's said in a social media post alongside the video. "This racing behavior is thought to be caused by dolphins trying to catch a food source, attempting to evade natural predators such as orcas, or meeting up with another pod of dolphins."
