Tattoos generally symbolize a specific meaning. Animal tattoos are great tattoos to get if you want your tattoo to hold a specific meaning. Each animal conveys something different. They are not gender specific and can be imprinted on any part of the body.
Peacocks are very charming and beautiful creatures. They represent beauty, dignity, pride and self assurance. Peacocks have a variety of colours on them which make tattooing them a lot of fun. This is indeed a gorgeous being to tattoo on oneself. One could also tattoo a peacock feather if tattooing an entire peacock seems too much.
Snakes are slithery and dangerous beings. They can injure humans with just one bite. Snake bites can be poisonous and fatal. Snakes are therefore tattoos which convey danger and fierceness of character.
