  • LIKE moths, the eyes of many pelagic and bottom-living decapods appear to glow brightly when viewed from the direction of illumination1. It has generally been assumed that the optical system involved is similar to that in nocturnal insects, that is, the superposition mechanism of Exner2. The essential feature of Exner's theory is that the optical apparatus of the cornea and crystalline cone refracts light through twice the angle at which it was incident on the cornea (Fig. 1a). Light from many… CONTINUE READING
