There is actually a more in-depth meaning to the skull tattoo designs than just fear, danger and death - and in fact it was not originally conceived as a symbol to represent any of these things. It was instead originally used to represent the symbol of 'great change'. In analyzing what them traditionally meant in ancient society we discover that it was related to the happening of great changes and it is highly probable that its association with death grew because of the fact that death is the greatest change that we will experience.
Today it is extremely unfortunate that the majority of the general public does not understand the true meaning of them, and when they see it they automatically relate the symbol to fear, danger and death. A lot of conservative people loathe the design because of its perceived meaning; however, if they were aware of the true meaning behind the design their views may be totally different.
If you decide that this type of design is the one for you, then your next step is to choose which genre you would like to go with. As the designs have been around for centuries the styles have somewhat evolved over time. The styles range from the old fashioned Jolly Roger, the pirate's flag with the skull and cross bones or perhaps you would prefer the bio-mechanical style of skull - the choices are extensive and totally dependent on your personal taste.
