It was early in the afternoon as you were prepared to go scuba diving for the first time. From what you heard from people around you, it was home of the jaw skeleton of the Megalodon. A giant prehistoric shark that use to conquer the entire ocean centuries after the dinosaurs died, so you were in for a bit of a treat.
You jump off the boat you were on, and start swimming as you had the scuba gear on, and spotted the shark jaw as you swam over to it. You gaze in brilliant joy after finding it, and noticed that one of its teeth was missing, leaving a small gaping spot. Just as you touch further, you accidentally scrape your arm against one of the teeth, causing a cut to sprout on your hand. You decide to get it patched up, so you swim back up to the surface, and grab the first-aid kit after getting back on the boat.
