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

Figure 4

Absolute (a) and relative (b) cone opsin quantum catch comparisons distinct geographical locations in Lake Malawi (Thumbi West and Zimbawe) and Lake Victoria (Makobe and Python). Relative quantum catch represents the quantum catch (photons) of each cone pigment normalized to the total quantum catch for all pigments.
