Over the weekend, thousands of common dolphins were spotted 9 miles off the coast of San Diego, engaged in an apparent feeding frenzy that stretched 7 miles wide and 5 miles long.
Dolphins usually travel in groups of 200 or less, but occasionally are spotted in pods of 1,000.
According to KFMB television in San Diego, experts estimated 2,000-3,000 in this “super pod,” but Capt. Joe Dutra, who piloted the tour boat that followed the dolphins for more than an hour, estimated the number closer to 100,000.
At times, the dolphins reached speeds greater than 25 mph, outpacing the boat while churning the ocean’s surface into a boil.
