They can be but most attacks are brought on by the diver. When you see one you'll notice their mouths are always open and they can look pretty mean with all those teeth sticking out. In truth they have to have their mouths open so they can circulate water over their gills so they can breath. If bitten by one, try and stay as calm as you can and it will let go after a short while, because while it is holding onto you it can't breath, so it will need to let go in order to start breathing again.Murfreesboro wrote:Oh my gosh!

It's only a guess, but the one that followed me up might have thought I was going to feed it. Divers have gotten many of the eels down there to become semi-tame and they will eat out of your hands.
