Down by my parents boat yard one summer when I first got into scuba, salt water, I had just gone down to clean out the intake for the lobster tanks. They would get loaded up with seaweeds etc. Only about 60 feet of water there but it was cooler water, and early spring, so the deeper the better as the fresh water is closer to the surface and you can loose lobsters that way.
I decided to roam a little as it didn't take long and had a full tank of air. I was headed away from our docks and up river a little. Now this is a big river,and to give you an idea how big it is and deep they run the nuke subs up it to the Groton Sub base. Anyhow, I'm not up in about 20 feet of water and rooting around in seaweed and kelp like stuff in quiet spot when all of a sudden right in front of me and all around is carcass of beef. My instincts were to get away from it, that creep factor you mention, only to run into more of them. Well I stopped dead, tried to figure it out and then realized that the Beet Brothers Super Market must of tossed a bunch of bad meat or had cleaned them off as much as they wanted and tossed them over board to be taken away by the out going tide. I never forgot that creep factor and can still see it. Not sure what I was expecting to be attached to it all, but it was something I never wanted to find in the water.
Anything dismembered, gets my attention in water or land.....
Funny or not what your mind does to you in unfamiliar circumstances.
