This pod of common dolphins surf on the bow wake of a boat off the California coast. Common dolphins are among the fastest of all cetaceans and can reach speeds of up to 25 mph. Getting an extra push from the surge from a boat gives them extra speed without extra effort, so it's no wonder dolphins love to ride the bow waves of boats.
