Cockeyed Squid <i>Stigmatoteuthis Dofleini</i>

Caption

The cockeyed squid Stigmatoteuthis dofleini has one normal eye and one giant bulging eye. New behavioral evidence collected by biologists at Duke and the Monterey Bay Aquarium Research Institute (MBARI) show that cockeyed squids' lopsided eyes evolved to spot two different sources of light available in the ocean's 'twilight zone'.
