Loch Ness Monster Sighting: A new image has popped up on the internet that experts say might just be the Loch Ness monster.

It's been a few weeks since an image that could be the Loch Ness Monster was caught on Apple Maps. Now an unusual sonar image is being examined because it may have caught Nessie.

Loch Ness Monster pictures are nothing new. Neither are Loch Ness Monster picture hoaxes. The most celebrated picture of Nessie was admitted to be a hoax by the lensman on his death bed. It was made of wood.

The sonar reading was taken by Skipper John Askew, who helms the flagship vessel for Jacobite Cruises. Askew took a screen shot of a sonar image that looks like a large and unusual object deep under water. The reading was taken near Urquhart Castle on the shore of Loch Ness.

Skipper John Askew said the reading is the "most unusual he's seen."

Satellite images spotted this month also claimed to show the Loch Ness monster. There have also been reports of other monster sightings off the coast of Australia.

In a statement Skipper John Askew, said: "This image certainly grabbed our attention. The Jacobite Queen spends every day sailing up and down the loch with the sonar on and this reading is the most unusual we have seen for quite some time. It's impossible to tell what we've picked up here, but along with those satellite images, you can't help feeling that reports of the Loch Ness Monster's demise may be premature. Nessie captures the imagination of people all over the world and, if anything, the speculation around lack of recent sightings has increased that interest."

The Loch Ness Monster has eluded searches using state-of-the-art sonar equipment, a yellow submarine, psychics, seers and witches. Loch Ness Monster sightings have been reported almost every year since 565 AD.

Nessie hasn't been seen in the past 18 months, which is the longest stretch of time that Nessie has been unreported since 1925. There were three Nessie sightings in 2013, but they were all exposed as fakes. One image showed a duck, a big and frightening duck, but a duck nonetheless, one image was actually a wave and one of the pictures was shot somewhere far away from Loch Ness.

Dr Robert Kenneth Wilson snapped the original "Surgeon's Photograph" of the Loch Ness Monster. It was in the Daily Mail on 21 April 1934. Wilson admitted on his death bed that it was a hoax.

Nessie has been spotted 1,036 times since 565AD.
