In 100+ dives in the BVIs, VIs, Cayman and Bonaire I think we have encountered 2 sharks. 1 a Lemon in BVI sitting under a ledge on my 3rd dive ever and the next year a Bull in St. Croix at the Pinnacle. I sucked down way too much air out of fear and the safety stop was a little shorter than usual smile Both times the dive masters were over the moon because they are both such rare events. Maybe not the lemon but I think they were afraid I would not dive again. I'm from Jax Fl and have a great respect for and healthy fear of sharks.
