Snake Tattoos
Snakes can symbolize various things, which is why they tend to make a popular tattoo.
When seen eating it's own tail in a clockwise direction (head to tail), snakes are seen as one's own life or rebirth.
Many civilizations worship snakes. You can find cobra wrapped around the neck of Shiva and Vishnu; temples are found with snakes. Indian cultures pray to the snake. They even have a special day devoted to them.
