Wild Dolphins play while scuba diving

We have been diving in Red Sea, nearby Shaab Bagul (Egypt, Safaga region). Shortly after descent to 12m (sandy bottom) group of 5 dolphins (1 young, 2 females, 2 males) came to investigate us. Our efforts to attract them for a longer play were rewarded, and the young one seemed to be happy while playing with us. I've decided to let my buddy play with dolphin, while I watched it from the distance (also for safety) and shot this video.
Hope you enjoy watching.
That was very exciting and heart warming experience, although it cost us a lot of air : )
