The National Ocean Service made the unusual declaration in response to public inquiries following a TV show on the mythical creatures.
It is thought some viewers may have mistaken the programme for a documentary.
“No evidence of aquatic humanoids has ever been found,” the service wrote in an online post.
The article was written from publicly available sources because “we don’t have a mermaid science programme”, National Ocean Service spokeswoman Carol Kavanagh told the BBC.
The inquiries followed May’s broadcast of Mermaids: The Body Found, on the Discovery Channel’s Animal Planet network.
That Animal Planet program about mermaids caused quite a stir about mermaids, as we PREDICTED. The show wasn’t a documentary. It was purely fictional, a bit like a “what if” type show. The disclaimer that it was fiction/speculation was not made clear. Or clear enough.
