Marine biologists at Duke University have discovered  that sea urchins are basically big floating eyeballs. Essentially their tubed-feet and appendages contain light sensitive molecules that allow them to essentially use their whole body for sight.

Scientists had conjectured the spines of sea urchins might then help them pick out relatively fine visual details by screening out light from off angles. If this proved true, urchins with densely packed spines would have relatively sharp vision.

TL;DR, invest in monocles!
