Sharks like to hang out in water several meters deep, so if the top of the reef is at least 5 meters deep, you may see smaller ones cruising around. Stingrays tend to like sand so they can hide, but can be seen cruising over the top of the reef. Jellies for sure, unfortunately, but they can be seasonal.

Answer:I don't really think you should go snorkeling where there's sharks around! What you could do is try to swim away from the shark before it catches you. Cuddly sharksThere is a real effort in the world's great diving spots - ex. Great Barrier Reef - to develop a new attitude to sharks. I snorkeled there recently for several weeks, would see sharks often (white tipped, black tipped, nurse, etc) and they would just swim by and not pay any attention to me. Sure there are sharks that if hungry will go after a human, especially if it thinks the human is a seal, but in general sharks are not that big, not that hungry, not that interested. Sharks have a role on the reefs and killing them off (as we have - many harmless sharks are endangered) is killing the role, and that threatens the reef.
