Register of 'official Loch Ness Monster sightings' hits 20
The Official Loch Ness Monster Sightings Register is 20 years old.
Inverness-based chartered accountant Gary Campbell, the keeper of the register, has logged more than 1,077 sightings since the record started.
He has accepted one sighting so far this year, from a visitor to the Highlands from Texas.
The tourist took photographs of a dark object which she said was just under the surface of the loch and following the boat she was on.
Last year, five sightings were accepted for the register - the most in 13 years.
Mr Campbell, who believes a large fish or eel is behind the monster claims, said the majority of sightings were not included because they could be explained.
He said: "Anything that is later proved to a hoax or can be subsequently explained is removed from the register.
"When I started the register I never expected to be doing it this long but after 20 years nobody has solved it - so I expect I will be doing this to the day I die."
