Though said to be long extinct, reports of megalodon sightings keep the world guessing
Don’t be fooled by altered photographs or misleading footage. The largest shark that ever lived is extinct and has never been seen alive by human eyes. Measuring up to 18 metres (60 feet), the shark’s size has been determined by the size of its teeth and rare fossilised sections of the shark’s spine.
If the giant shark still existed it would need a healthy supply of extremely large animals like whales to survive. It is thought, however, that megalodon’s extinction allowed the evolution of large filter-feeing whales. If megalodon still existed, whales probably would not.
