Biology:List of alleged megalodon sightings

From HandWiki
Reconstruction of a prehistoric megalodon compared to a human. The modern presence of comparable predatory sharks has been alleged, but never confirmed.

The megalodon was a large shark that existed in prehistoric times. It is considered to have become extinct about 2.6 million years ago.[1] Poorly documented sightings of large sharks measuring anywhere from 10 to 90 meters (40 to 300 ft) have been alleged throughout the 20th and 21st centuries. Such[2][3] megalodon sightings, abbreviated as "meg sightings",[4] are not regarded as credible by scientists and most other researchers.[5][6]

List

  • One Polynesian myth regards a 30-meter (100 ft) shark called "Lord of the Deep".[2][3]
  • The "Black Demon" (Spanish: El Demonio Negro) of the Sea of Cortez is usually considered to be a black shark, and less commonly a whale, living off the coast of Baja California in Mexico. It is said to measure about 60 ft (18 m),[3][7] similar to the estimated length of the megalodon.[8]
  • In the 20th century, sailors and crayfish fishermen of the waters off Australia respectively told Cartmell[9] and Stead[10] about what they saw. In the former case, the sailors alleged seeing a white shark near the Great Barrier Reef that rivaled their boat in size, with the boat measuring 85 ft (26 m). In the latter case, the fishermen alleged seeing a pale white shark near Broughton Island that was about 115 ft (35 m), and had a head that was not shorter than the roof of a wharf shed near Nelson's Bay. They were consequently too terrified to return to the area.[3]
