Sure Medusa has snakes for hair but why stop with snakes. Imagine a gorgon with swan necks instead of snakes... or ferrets. Heck you could even have deep sea annelids and a gorgon that breaths sulfur and fire. I can think of hundreds of variations just off the top of my head (see what I did there?). Eels, centipedes, velvet worms, or combinations and chimera gorgons.
