my experience has been that sharks are really more curious than anything else. on my first checkout dive we encountered a 6' nurse shark lying under the bow of an old barge. i think she was as frightened of us as we were of her and she kept her distance. however, my most memorable encounter came last year when i was spearfishing around an old liberty ship at 100'. as i was swimming along looking for fish, a 7' bull shark swam up from behind and "brushed" me. can you say abort dive?? thats exactly what happened. my dive instructor said that it was not unlike a dog sniffing someone it doesn't know. a buddy of mine actually had a bite taken from a snapper on his stringer on that same dive.
