Abstract

The spectral sensitivity of the retinal photoreceptors in 31 fish species belonging to five families from the Sea of Japan was studied by microspectrophotometry. All species inhabit the subtidal zone, often occurring at shallow depths. The photoreceptors of more than half the species had porphyropsin, which makes the retina more sensitive to long-wave light. Some species displayed a remarkable shift of spectral sensitivity to the long-wave end, which is correlated with life in shallow waters and with the presence of optically dense orange corneal filters. The results further support the notion that the presence of porphyropsin in the retina is necessary for not only freshwater fishes.
