The grapefruit-sized eyeball which washed up on a Florida beach last week came from a swordfish, according to experts.
The giant body part had been the source of much speculation last week when it was found at Pompano Beach, north of Fort Lauderdale.
Wildlife officials said today the eyeball was most likely cut from a swordfish and tossed overboard by a fisherman.
"Experts on site and remotely have viewed and analysed the eye, and based on its color, size and structure, along with the presence of bone around it, we believe the eye came from a swordfish," according to Joan Herrera of the Fish and Wildlife Research Institute in St Petersburg.
"Based on straight-line cuts visible around the eye, we believe it was removed by a fisherman and discarded."
Swordfish can reach a whopping 1,100 pounds (500 kilograms), and are frequently caught off the coast of south Florida, the agency said.
The agency said genetic testing will be done to confirm the identification.
