SLightly off-topic, but since we got lucky recently... A friend and I just got these pictures on Saturday. This little guy was bold enough to be out in the open, but he was also timid and obviously more concerned with not getting attacked than attacking me (based on the interations I had with him, this is difficult to judge from the pictures).

I tested a few things out for effect. I found that closing my eyes for a period had no effect on him (probably explained by the lack of visoion to see my eyes, and/or that the closing of eyes, and eyelids in general, aren't a feature eels have), but when facing each other in another location for a while, and testing out an intentional look-away, he took the opportunity to go under me and get to another part of the wreck. I left him be at that point.
What a beautiful creature to see out of its hole though.
The largest we've seen was what I'd call an easy 9 feet. I tried hard to judge, too, but all I could come up with was that he was longer than any diver plus their fins down there. There was a group looking at his head sticking out of a hole, so I went around them, and down behind the reef only to find a massive cave area where the rest of his body was completely exposed. I'm not sure the Moray realized how exposed he really was, or he probably didn't care. They hide for ambushing fish, not as much to protect themselves when they get that size (from what I can tell).
No one told the Morays get that big, though probably no one I dive with knew that they did. A recent check on a website for green morays listed 8 feet as about maximum. This was off of Fort Lauderdale.
I realized, looking closely at that very thick, long purely-muscular tail that if an eel that size wanted me, an eel that size was gonna have me, and a good sized dive knife didn't mean much despite all the bravado I hear from divers and their shiny toys. Would I fight? Yes, but I'm just sayin'...
Best,
