The Florida Fish and Wildlife Conservation Commission said Monday 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 the identification.
Wildlife officials say swordfish are commonly fished at this time of year in the Florida Straits offshore of South Florida. That's where the softball-sized eyeball turned up Wednesday.
The discovery and photos of the big eye created a buzz on the Internet.
