Nagin

A female snake in a human form. Usually only seen in typical Bollywood movies, no one in this world has, however, ever seen one for real. Very seductive, beautiful, and dangerous in nature, this creature is also often referred to as Vish Kanya (as very aptly portrayed in the series- "Chandrakanta"). Myth is to believe only on female snakes to be called as a Nagin but this wonderful creature could have easily replaced the beautiful Mermaids in Pirates of the Caribbean (On stranger tides).
