The Bermuda Triangle, also known as the Devil's Triangle, is an undefined region in the western part of the North Atlantic Ocean, where a number of aircraft and ships are said to have disappeared under mysterious circumstances. The triangle does not exist according to the US Navy, and the name is not recognized by the US Board on Geographic Names. Popular culture has attributed various disappearances to the paranormal or activity by extraterrestrial beings. Documented evidence indicates that a significant percentage of the incidents were spurious, inaccurately reported, or embellished by later authors. In a 2013 study, the World Wide Fund for Nature identified the world’s 10 most dangerous waters for shipping, but the Bermuda Triangle was not among them. Contrary to popular belief, insurance companies do not charge higher premiums for shipping in this area.
