The Florida Fish and Wildlife Commission said Monday they believe the specimen came from a swordfish. The experts said they based their conclusion on the eyeball's color, size and structure, along with the presence of bone around it. Genetic testing will be done to confirm that.
A man named Gino Covacci became a national sensation after he found the softball-sized eyeball last week. It was immediately sent to a Florida lab.
Researchers believe a fisherman removed it before getting rid of it. Swordfish are commonly fished off the shore of south Florida during this time of year.
