If you are already thinking of what to wear on October 31, you may be convinced that this discovery is merely a Hallowe'en prank.
But the identity of this curious specimen - apparently found washed up on a beach - has incited much online debate.
Paul Jones posted a video of the 'dead mermaid' to Facebook, saying he found it lying on the sand at Great Yarmouth.
And the scepticism over the verity of the footage began.
Despite the skeletal-like remains, some commentors claim the remains are more likely that of a dead seal.
Many others take the view that someone is trying to raise a few heckles in the run up to the scary night.
What do you think?
