Hammerhead shark
Out of the nine species of Hammerhead sharks,    three are dangerous to humans:   the Scalloped,   Great , and  Smooth Hammerhead.     The Great and Scalloped are listed as endangered by the International Union for the Conservation of Nature, while the Smalleye  is listed as vulnerable. This is because of over-fishing for the fins of Hammerhead sharks, which are used in shark  fin   soup.      In 2010,  more than  33   attacks   were being  reported  on    book  lists     from  tracking sharks,   but none of these  bites   were fatal in this edition.
