An Evaluation of the Role of Sensory Drive in the Evolution of Lake Malawi Cichlid Fishes

Comparison of cichlid cone opsin absorbance spectra in various environmental light environments. (a) Absorbance spectra for the six primary classes of cichlid cone opsins. (b) Relative irradiance measures of downwelling light at various depths at the Zimbawe Rock in Lake Malawi. (c) Comparison of the relative irradiance spectra for two Lake Malawi habitats (Thumbi West and Zimbawe) and two Lake Victoria habitats (Makobe and Python). Relative irradiance represents the proportion of total downwelling irradiance (photons/cm/s2) normalized to the wavelength of maximum transmission.
