Hi Francois, thanks for these infos, didn't know that they were always there, when I was a child and when we went to tamarin, nobody talked about the dolphins. Have they been newly discovered there or before only they people in tamarin knew about it but didn't know it could be a great tourist attraction ?
I find dolphins are really fascinating, thats why I ask so many question

hope you don't mind

Tell us a bit more of you, are you a skipper or do you offer dolphin sightseeing tours ?
