Playful dolphin bites my fins!

On our way to Dassen Island my girlfriend and I came across a pod of dusky dolphins about 3km out to sea. They were very playful and inquisitive so I jumped in the water with them. For about 20 minutes there were between 4 and 8 individuals around me the whole time, then, one by one they left until only one remained. He stayed with me for about another 30 minutes following me on dives and nipping at my fins. This clip is a short unedited version of the encounter.
