A mysterious sea creature featuring what appear to be horns on its head was discovered in the advanced stages of decomposition along the shoreline of Luis Siret Beach in Villaricos, Spain, on Thursday. A woman first discovered the head and then found the body farther down the beach, according to ThinkSpain.com. The entire carcass with the head stretched 13 feet.“ A lady found one part and we helped her retrieve the rest,” said Maria Sanches of Civil Protection in Cuevas. “We have no idea what it was. It really stank.” The find caused widespread speculation as to what it could be, some humorously suggesting it was a link to the Loch Ness Monster or was some sort of sea dragon or water dinosaur. Others surmised it was a mutant fish or some sort of shark species. The best guess here is an oarfish. More Images on Grind TV.
