A fanged "monster" with no eyes which washed up on a beach after Hurricane Harvey has left experts scratching their heads.
The colossal creature was found rotting on a beach near Houston after the megastorm which ravaged the southern US, reports The Sun.
The mystery beast was discovered by conservation group the National Audubon Society who posted the startling snaps on social media.
The creature's species still has not been confirmed although many experts believe it is a fangtooth snake-eel.
Preeti Desai, the National Audubon Society's social media manager, spoke about finding the dead beast.
"We were on a beach in Texas City and saw this thing from afar so I got closer to figure out what it was," Ms Desai said.
"I've already got a huge interest in wildlife, especially birds and ocean creatures, but it was so unexpected to see it there on the beach.
"On first glance it looked like something from the deep sea to me.
"My initial thought was it might be a sea lamprey but when I got close I realised there was no way that was what it was, particularly based on the mouth.
"We squished it around a bit, and even turned it over but couldn't come up with any other ideas."
After failing to identify the fish, Ms Desai posted the images on Twitter asking for help.
"This is the kind of thing that's perfect for Twitter - there are so many scientists and researchers on the platform and they're very willing to jump in and figure out things like this," she said.
"So I put the photos out there and the guesses started coming in. One of the first few guesses suggested some sort of eel.
"I mentally smacked my forehead, because once that was suggested I could absolutely see the eel shape.
"But when I think of an eel, I think of it in the ocean, hiding among coral or rocks, so I hadn't made the connection while I'd been on the beach."
