tiger-sharks & hammerhead

Sharks are NOT the devils of our seas ! look at these pictures and see how close and friendly contacts we had with the biggers and most feared of them !
They NEVER intentionally attack people ; what the media call a shark "attack" is really a shark "mistake" : we are NOT a food source for them.
In the opposite, the total number of sharks killed annually is probably well over 100 million !!
But take care if you eat them ! alarming concentrations of mercury are found in sharks : this can cause neurobiological deseases, and also sexual dysfunction and sterility !
