It was discovered by two nurses in the town of Kitchenuhmaykoosib in Ontario, Canada, while they were out on a walk with their dog. The two took some photographs of the dead animal pulled out by their dog from a lake, then they left it alone.
When locals went back to retrieve the body, it was gone.
The photos taken by the nurses have now been posted on a local website and then have triggered mass speculation about what kind of species the animal is.
Many people have suggested the animal could be a new "Montauk monster" - due to the similarities between these photographs and those of a different creature which washed up in Montauk, New York, in 2008.
