Mysterious Horned Sea Monster Identified?

August 23, 2013

That mysterious horned sea monster that washed up onto Luis Siret Beach in Villaricos, Spain last week may have been identified.

Some people thought it may have been an oarfish, or a mutated fish affected by pollution, but two experts have determined that it’s a shark.

Possibly a thresher shark.

“That is definitely a shark skeleton,” Florida State University ichthyologist Dean Grubbs told NBC News. “The elements toward the back were confusing me, but those are the lower caudal fin supports. The ‘horns’ are the scapulocoracoids which support the pectoral fins.”

Grubbs specializes in the biology of fish species, especially sharks.

And David Shiffman, a University of Miami shark researcher, agreed. At first he said it was “hard to tell… but the official guess that it could be a thresher shark seems plausible.”

Shiffman had also been in the oarfish camp when in a Twitter exchange with NBC News. “Certainly the tail looks oarfish-y,” Shiffman wrote. “It maybe could be a thresher shark—but nothing else.”
