In total, 11 different subsets of cone pigments were identified across the species studied. The number of individuals that exhibited each pigment subset, the number of cone classes included in each subset and the frequency of each cone pigment subset per species are indicated. The λ_max (nm) values of cone pigments that comprised each subset are given (means ± SD).
