Figure 1

Visual pigment absorption spectra based on the microspectrophotometry of the Lake Victorian cichlid Haplochromis pyrrhocephalus (van der Meer and Bowmaker, 1995). The single cones (blue) contain a pigment with peak sensitivity at 462 nm, while the double cones contain pigments with peak sensitivity at 539 (green) and 595 (red) nm. The 595 nm pigment is coded for by the LWS opsin gene. The inset shows the square retinal mosaic typical of cichlids where single cones are surrounded by double cone pairs.
