However, it was the notion of the Loch Ness monster as a prehistoric reptile that really captured the public’s imagination in the 1930s. Each time, the person claimed the idea was original. For example, the idea that the Loch Ness monster was originally a swimming elephant from a visiting circus, resurfaced three times, in 1934, 19. Some theories have been reinvented independently, showing the ingenuity of each generation of Nessie inventors. Many early suggestions by foreign zoologists implied they thought the loch was saltwater, which explains suggestions of sunfishes, whales, sharks and rays. The people who came up with these theories were not necessarily that familiar with the loch. There have been over 85 theories of what the Loch Ness monster is, ranging from the prosaic ( wind slicks, reflections, plant debris and boat wakes) to the zoological implausible (anacondas, killer whales and the ocean sunfish) to the frankly bonkers (ghost dinosaurs). The witnesses certainly saw something, but what? Although the video clearly shows a moving v-shaped wake it does not reveal the underlying source. The latest report, accompanied by a video, is of a 20-30ft long creature occasionally breaking the water’s surface. Reports of Loch Ness monster sightings keep coming.
