Spectral Sensitivity of the Common Prawn, Palaemonetes vulgaris [PDF]

open access: yesThe Journal of General Physiology, 1968
The vision of Palaemonetes is of particular interest in view of extensive studies of the responses of its chromatophore systems and eye pigments to light. The spectral sensitivity is here examined under conditions of dark adaptation and adaptation to bright colored lights. In each case the relative number of photons per one-fiftieth sec flash needed to
