Scientists are investigating a deep-sea mystery after the remains of a bizarre ocean creature washed up on a remote beach.
Bjorn Dihle made the bizarre discovery while kayaking in Berners Bay, Alaska, nearly 40miles from the nearest town.
He initially thought the 5ft-long white object was a type of ray but soon realised he had found the innards of something much much larger.
The wilderness guide said: “When I got to the beach, I quickly realized it was the internal organs of something very large.
“The organs looked and felt like a decomposing liver, and smelt like a fish hold that hadn’t been cleaned in a while – a bit like ammonia.”
Experts say they can’t be sure what Bjorn found without a tissue sample, but some think it may be the liver of a Pacific sleeper shark.
But it would be bigger than any that Bjorn – a former commercial fisherman – had ever dragged from the deep.
He said: “I’ve caught a handful of sleepers while commercial fishing for halibut but the biggest was only around eight feet.
“This individual must have been significantly larger. My first thought was whale guts as it was too large for any other marine mammal.”
