They generally don't bother divers, but Babiarz did get one scare. As he probed in the darkness for teeth, he felt something rubbery and hard. First I though it was an alligator, but it turned out to be a clay bank, thank God. Crabs are a bigger problem. There were huge crabs all over the place.
Crabs stand their ground.
A crab once grabbed one of his diving partners by the leg. When they grab hold they don't let go. Babiarz draws the line at diving for sharks' teeth in South Carolina's Morgan River. It's just too deep and dangerous for his taste. The Morgan is so dark, some divers don't even bother with a light.
