The only known mechanism for color vision requires spectrally diverse photoreceptor types (1). However color vision comes at a cost: a reduction in the signal to noise ratio in low light conditions and angular resolution in each spectral channel. Coleoid cephalopods (octopus, squid, cuttlefish) have a single photoreceptor type (2,3,4) and lack the ability… CONTINUE READING
