According to the Guinness Book of World Records, one of the largest sharks ever caught was 36’ (10.9 m) long. It was caught in Port Fairy, Australia in the 1870s. The size was brought into question when James Randall of the Natural History Museum of London measured the teeth and the jaws and determined the shark to be only 16 ½ ‘(5m). Randall based his observations on the size of the teeth back in the 1973. Not all agree with Randall’s methods and determination, but it is likely the shark was not 36’ in length.
