The underwater abominable snowman, or underwater ABSM for short, is a sea serpent reported from the Bahamas. It was sighted and named by diver Bruce Mounier in 1968, whose account was first published in Charles Berlitz’s 1977 book Without a Trace.[1]
“
We were south of Great Isaac Light, near the drop-off. I was looking at the bottom while I was being trolled along on a line behind a 30-foot boat built especially for diving and salvage work. I could see a sandy bottom at 35–40 feet. I was deep enough to see ahead of the boat and some sort of round turtle or big fish — about 200 pounds — became visible and I went lower to get a good look. It turned and looked at me at a 20° angle. It had a monkey’s face with its head protruding out in front, a much longer neck than a turtle — four or more times the length of a human neck. It rotated its neck like a snake as it watched me. The eyes were like those of a human being, but enlarged. It looked like the face of a monkey with specially adapted eyes for underwater vision. When it got a good look at me it took off — using some form of propulsion that came from underneath. [...] I’ve caught and sold hundreds of turtles and this was definitely not one. I think it is some unidentified species, it may be a newly developed one, or a very old one we haven’t seen before.
