Giant 'mystery eyeball' discovered on South Florida beach:
"The discovery of an enormous eyeball on a South Florida beach begs a very pertinent question: What kind of creature did it belong to? The "mystery eyeball," as it's being referred to by the Florida Fish and Wildlife Conservation Commission, was found Wednesday by a beachcomber on Pompano Beach."
The only person quoted in this story who knows what he's talking about is George Burgess, the marine biologist who runs the International Shark Attack File. He suggests a bigeye thresher shark, which looks like this:
Update: Further speculation in Saturday's Christian Science Monitor:
"An assistant biology professor at Florida International University in Miami on Friday said the blue eyeball may have come from a deep sea squid or a large swordfish. Heather Bracken-Grissom says the lens and pupil are similar to the shape of a deep sea squid's eye. She notes that the squid's eyes can be as large as soccer balls."
