The modelling of optimal visual pigments of dichromatic teleosts in green coastal waters

We have constructed a computer model that attempts to predict which pairs of rhodopsins are most suitable for making various luminosity and chromaticity discriminations in green coastal water. The model, which is based on the statistics of photon capture by retinal photoreceptors, predicts the optim...

Zusammenfassung:	We have constructed a computer model that attempts to predict which pairs of rhodopsins are most suitable for making various luminosity and chromaticity discriminations in green coastal water. The model, which is based on the statistics of photon capture by retinal photoreceptors, predicts the optimal visual pigment pairs for different visual tasks. The results obtained from the model compare well with the rhodopsins possessed by dichromatic fish living at moderate depth in green coastal water
