Abstract
The compound eye of the galatheid crab Pleuroncodes planipes has been studied by means of visual pigment extractions and spectral sensitivity measurements under various conditions of adaptation. A photosensitive pigment with maximum absorption at 503 nm was identified. Its chromophore is retinal. The spectral sensitivity maximum is near 523 nm in the dark-adapted eye. Selective adaptation experiments suggest that the apical region of the eye has a homogeneous receptor population. The spectral sensitivity characteristics of P. planipes seem to be an adaptation to its mainly benthic life.
