This is a pic of a Great White Shark. Tattoo'd by Heath at Something Wicked, Lincoln, UK.
Sharks are my worst fear, and the thought of ever seeing one petrifies me. I have suffered with Selachophobia since I can remember, and had this tattoo put on my arm where I can see it whenever I go swimming.
Psychologically, this is my own deliberate way of scaring myself by facing my fears when in the water.
