Do they chum the water for the shark dive?
No, they bring a 5 gal buck of fish heads/ guts, but it stays closed and on the sea bottom until almost the end of the dive. Then they open it and it is utter bedlam for a few seconds while all of the sharks try and fit into that bucket at the same time!! It's basically a small snack so that the sharks don't get used to being fed. Once the bucket is clearly empty the sharks leave and you swim over the area looking for any fallen teeth for a few minutes before heading back up to the boat.
