A fisherman was left stunned after stumbling across an alien-looking creature with tentacles.

Roman Fedortsov, regularly goes viral for the “bizarre” creatures he finds in the deep sea. Previously, the 39-year-old from Murmansk, Russia, captured an unknown fish with a bloated, puffy mouth, which many online users compared to “bodged lip fillers”.

Now, he has shared an “alien from the depths” among his 642,000 social media followers, and has racked up 344,000 views and more than 12,000 likes.

The creature is seen poking its body and tentacles out, almost like a tongue, before receding back into its shell. Social media users flocked to the comments section on his posts to give their mixed reactions.

One person described the creature as a “big a*** barnacle", while another user said: “With lemon and chili it has to taste really tasty.”

But others doubted they would enjoy the deep sea find, saying: “I’d have to be hard-pressed to eat that.”

Another person added: “What in the!?! Not in this hundredth dimension of the grey side of the matrix. No,”

One user said: “Scary, turn it off.”

Roman, who also catches cod, haddock and mackerel, has previously found a fish wearing lipstick, one with “cheeseburger” teeth and another that looked like a baby dragon.

Meanwhile, the Mirror reported how a man who found what he thought was a "sea monster" has been left puzzled after a number of experts were unable to identify it.

Dubbed the "Salish sea monster", the creature was discovered by chance while Eric Evans was walking with his brother close to where the Elwah River meets the Salish Sea in the US state of Washington. But after taking photographs of the beast and then showing them to wildlife experts, he was left none the wiser.

He showed the images to his former colleagues at the Olympic Coast National Marine Sanctuary, but left without an answer and now an expanding group of people have joined in the debate about what the animal’s true identity is – with no clear consensus, but plenty of theories emerging as to its origin.

A spokesperson for the Washington Department of Fish and Wildlife said: "I shared the images and video with both fish and wildlife biologists in our department and we’re similarly stumped! Basically, the conclusion from our biologists is that this is unfortunately too far decomposed to identify."

And Casey Cook, who directs the Marine Life Center at Bellingham, some 65 miles north-west of the sighting, also examined the pictures said some parts of the body were characteristic of the shark family, while others were more typical of a seal or whale, adding: "Long story short – the big picture is very conflicting and I have no answer for you."
