Mysterious Sea Creature Washes Up On Shore, Its Huge Size Startles Beachgoer 02/25/21 AT 8:11 AM A beachgoer in the U.K. was shocked after she came across a mysterious sea creature that washed up on the shore Monday. Holly Asargiotakis said she was "startled" after seeing the enormous animal. Asargiotakis was walking with a friend on Ferring Beach in Sussex when she spotted the huge creature. She said the beach was full of dead crabs and her friend's dog ran toward an eel-like creature lying on the shore. The 29-year-old hairdresser said the creature was 4-6 feet long. "Dash went up to it at first, probably thinking the same as us, then we kept him away from it. He was very interested," Asargiotakis told the Argus. "We didn't know what it was at first. A lot of people have been saying it's normal, but I'm really not a fan of the sea."
