                                                Their fearsome features, gigantic size and fierce array of teeth,
                                                alongside fictional films such as Jaws, have painted a rather poor
                                                picture of these misunderstood fish. Although shark bites do
                                                happen, they are very rare. In 2013 there were 53 unprovoked
                                                shark attacks in the USA, two of which were fatal. Compared
                                                with the amount of people in America who swam in the sea
                                                throughout the year, that number is very small.
                                                  The truth is that sharks don’t want to eat us. We aren’t fatty
                                                enough for their nutritional needs and we have too many bones

                                                the usual hunting strategy of the great white – ambushing and
                                                rushing the prey from beneath. If they really did believe we were   Coral
