I think we've seen some type of shark almost every trip, even this past trip. Nurse, reef (black tip), lemon. Always smaller ones, except for some large nurse sharks off the cay of Cinnamon Bay. They don't care about you. About 15 years ago we saw my wife's friend on Cinnamon, "they said" they saw a small hammerhead on the backside of Waterlemon Cay, dunno? A large tuna swam by me in the same spot where the big drop off is, that startled me! BUT, they are there and we like seeing them.
