Physical Features:

The megalodon is believed to be the largest fish that ever lived with the average mature adult meg growing to around 10.2 metres (33,5 feet). An infant meg is around  2 metres (6.5 feet).The largest meg was probably around 17.7 metres (58ft). The average meg is three times longer than the largest recorded great white shark. Megalodon teeth can reach 18 centimetres long.

It is estimated that its jaw would span 2.7 by 3.4 metres wide (big enough to swallow two adult people side-by-side). The meg had around 276 teeth. Recreations of the shark's bite force suggest that it may have been one of the most powerful predators ever to have existed. Megalodon had a bite force of between 108,514 and 182,201N whereas humans have a bite force of around 1,317 N. Despite its constant comparison to Great White Sharks, the meg likely had a much shorter nose when compared with the great white, with a flatter (almost squashed) jaw. Like the blue shark, it also had extra-long pectoral fins to support its weight and size.
