Only on the second dive
Even if your first dive goes well, there’s no guarantee that your subsequent trips into the dark abyss will be just as good. Well, unless you dive in the same spot at around the same time with the same people, then maybe, just maybe, you’ll make it out in one piece. This guy’s second dive was a pretty freaky one.
After descending to 135 feet, they found a group of bull sharks just 50 feet below them. For those who don’t know, bull sharks are the most dangerous type of sharks to humans. They usually hang around in shallow water, which is probably why the OP was shocked to see them so deep.
