Chris Crane, 61, was walking with wife Amanda, 59, when they witnessed a large black figure in the distance of a Cornwall beach and took pictures of the bizarre discovery to post to social media for further thoughts.

Chris told the Metro newspaper: ''At first I thought it might be a dolphin or a seal, but as I got closer I could see it was something a bit bigger and an odd shape.

''Some suggested it could be a Cornish sea monster and others have said it could be someone's mother-in-law but I'll take that with a pinch of salt. I thought it was all very odd.'''

Chris has sent the pictures to experts for further clarification.
