What does a sea Serpent look like ?

Where can I see a pic. of one ?

If you go to rcdb.com and search for Medusa at SFMW, you can see a picture of one. It looks almost like a cobra roll, but instead if doing a half corkscrew in the opposite direction, it continues into another half corkscrew, and finishes with a half loop.
