The long range aim of this research program was to investigate the mechanism and biological significance of the polarized light sensitivity of arthropods first demonstrated in the honey-bee by Karl von Frisch in 1948. The operational objectives of the work naturally developed in ways which were not completely anticipated at the beginning so that three related, yet distinct, lines of research were in fact pursued under the subject contract. Their objectives were 1 electrophysiological study of arthropod compound eyes with particular reference to their sensitivity to plane polarized light, 2 measurement of polarization of natural submarine light as well as the factors which affect it and 3 analysis of polarized light orientation polarotaxis in aquatic animals both in the laboratory and in the field.
