Sharks. My son seemed to have no fear of them and, to my thinking, was quite reckless in his eagerness see what was down there. He'd just jump in and swim to the bottom first thing all by himself. I don't know, maybe he was just braver than I am.
When I was a kid I was so afraid of darkness. My mother refused to leave a light on for me. I put night lights in my children's rooms and they could not have cared less. If the bulb burned out it was no big deal. I think they were more stable and secure children that I was all those many years ago.
