The great white shark can be found in the coastal surface waters of all the major oceans. He is mainly known for it’s size, with the largest individuals known to have approached or exceeded 6.1 m (20ft) in length, and 2,268 kg (5,000 lb) in weight.
On the other hand, Megalodon is an extinct species of shark that lived approximately 28 to 1.5 million years ago, during the Cenozoic era. Fossil remains suggest that this giant shark reached a maximum length of 14-18 meters (46 – 59 ft.); It is also regarded as one of the largest and most powerful predator in vertebrate history.
Scientists suggest that the megalodon looked like a stockier version of the great white shark; however, comparing it’s size, the megalodon was bigger! In fact the great white shark’s size is the same as a megalodon’s penis (clasper).
