Mysterious Huge Eyeball Likely Giant Squid's

A mysterious eyeball that washed ashore this week on a South Florida beach belonged to either a giant squid or swordfish, marine biology experts believe.



Associated Press reports that after some discussion with colleagues, Florida International University in Miami assistant biology professor Heather Bracken-Grissom came to the conclusion. She informed AP that the lens and pupil match those found in a deep sea squid's eye. She notes that a giant squid's eyes can be as large as soccer balls and they easily dislodge.

Dan-Eric Nilsson of Lund University's Department of Biology and colleagues recently wrote about such eyes in the journal Current Biology.

Nilsson and his team wrote, "The eyes of giant and colossal deep-sea squid are 27 cm (10.6 inches) in diameter. Modeling suggests that the huge eyes are uniquely suited for spotting sperm whales."

Squid can regenerate body parts, and many marine animals can regenerate their eyes, so I can only hope that the one who lost this eye is still in the water of the living and will soon have a new eye.

Here we recently reported that regenerated body parts are not as good as the originals. Nevertheless, any functioning part is obviously better than zilch.

The giant eyeball saga began this week when the Florida Fish and Wildlife Conservation Commission posted a photo of the big eyeball at Facebook with the following: "The FWC Tequesta Field Lab received a call that a citizen from Pompano Beach found what appeared to be a giant eye. Our staff in South Florida picked it up and placed it on ice. It will be sent for possible identification."

The eyeball is now at a research facility in St. Petersburg.
