Whale watchers were treated to an “extraordinary sighting” recently, as a northern right whale dolphin joined their catamaran for a bow ride off Dana Point, California.Video shared by Capt Dave’s Whale Watching shows passengers bending over the bow rail, as the finless dolphin swims with a pod of common dolphins. The beautiful creature is also seen in some underwater shots.“The dolphin even turned on its side to look at passengers on board!” a crew member said. “Once in a while, a few common dolphins would swim over to check out the new visitor.”The staff said that it was only their second sighting in over 20 years.
