Footage has emerged from the US of a humpback whale off the coast of California slapping its pectoral fin into the sea and breaching the surface, apparently to show off for the camera above it. <br /> <br />The video, filmed off Newport Beach towards the end of October, shows the whale hanging around at the surface, which it reportedly did for more than an hour. <br /> <br />++CLIENTS PLEASE NOTE: MUSIC IS ROYALTY FREE++
