“Experts on site and remotely have viewed and analyzed 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,” said Joan Herrera, curator of collections at the FWC’s 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.”

Genetic testing will be done to confirm the identification.
