Eyestalk movements induced by polarized light in the ghost crab, Ocypode quadrata.
Differential visual sensitivity to vertical and horizontal linear polarization is shown in the light-induced eyestalk deviations of Ocypode quadrata. Responses with the e-vector vertical averaged about 6 degrees greater than those with e-vector horizontal. This difference approximates the relative eyestalk deviation induced by unpolarized light intensities having a ratio of 3:1
