Polarization Sensitivity in Fishes

In optomotor experiments, the post-larvae of the coral-reef fish Premnas biaculeatus proved to be polarization sensitive. Also in optomotor experiments, the polarization sensitivity of the planktivorous fishes Atherinomorus forskalii and Sparus aurata was studied. Atherinomorus forskalii was only polarization sensitive if UV light was available, while Sparus aurata was not sensitive to linear polarization.
